IDEA 2019.2 doesn't open old projects

Eduard,

Do you have the HaskForce plugin installed? If yes, the issue is caused by this plugin. Here is related YouTrack item: 

https://youtrack.jetbrains.com/issue/IDEA-219106

I had the same problem

@Newcih2017

Have you tried to open a project with plugins removed? 

Also, try to add -Dide.mac.file.chooser.native=false in Help | Edit Custom VM Options and restart IntelliJ IDEA. Does it make any difference?

What is your OS? 

I have the same problem, in MacOs, after closing PhpStorm the project list gets empty

I'm facing the same issue. Today I installed Toolbox App and updated all my IDEs (phpstorm, webstorm, pycharm and golang) to my latest version 2019.2. Now I can't open any of my old projects. I uninstalled phpstorm from toolbox, deleted phpstorm preferences, cache, application support and log files, manually installed the 2019.2 version with no plugins installed and open button is not doing anything. btw I'm on mac.

@Konstantin Annikov

Yes, I had HaskForce plugin installed, but on restart IDEA was asking to disable it and I did it. I wasn't able to open projects after this final restart with HaskForce disabled.

Please try to add -Dide.mac.file.chooser.native=false in Help | Edit Custom VM Options and restart IntelliJ IDEA. Does it make any difference?

Do you run macOS 10.15 beta 5?

@Konstantin Annikov with this option IntelliJ IDEA offered to convert old project and after conversion opened old project. Thank you.

I'm using MacOS 10.14

@Eduard Luhtonen

Please track https://youtrack.jetbrains.com/issue/IDEA-219856 for updates. 

If it is possible, please attach a sample project which cannot be opened inside the YouTrack item. 

@Konstantin Annikov 
I added that setting to PHP Storm and after closing the IDE the list of current projects is still empty.

My Mac OS Version is 10.14.5, a dev buddy that works with me has the same problem

Felipep86, your issue looks different. The original thread is describing the problem with the macOS file chooser not opening projects. While you have a problem with the recent projects list? Please report a separate bug at https://youtrack.jetbrains.com/issues/IDEA with the logs (https://intellij-support.jetbrains.com/hc/articles/207241085) and the screenshots attached to clarify the problem. Thank you.

-Dide.mac.file.chooser.native=false  works for me;  

I'm using MacOS 10.15 beta 5

I had the same problem.  Workarounds mentioned here did not work for me, however I was able to open the project after updating the Kotlin plugin.

I had the same problem on Mac. After upgrading all plugins the problem is resolved.

I upgraded to Catalina and now Webstorm doesn't work me! When I open existing projects from the list I get this error message:

I tried to use "-Dide.mac.file.chooser.native=false", but see no difference. And when I try to open any folder from /Documents Webstorm doesn't show any files, it's empty...

Also, I disabled all plugins, restarted and it didn't help.

@Dementorvinegar

Unfortunately, there are some major compatibility issues with macOS 10.15. They will be addressed in 2019.2.4 version.

For now, make sure that WebStorm can access all of its folders (macOS or other software is not blocking it) including the ones mentioned in https://intellij-support.jetbrains.com/hc/en-us/articles/206544519-Directories-used-by-the-IDE-to-store-settings-caches-plugins-and-logs

I'm sorry for the inconvenience.

Konstantin, thanks for a quick response! Do you know how soon 2019.2.4 will be released?

There is no release date for now. You can try to see if the error is fixed in 2019.3 EAP version of Webstorm:

Konstantin, in 2019.3 EAP the issue is fixed! Thanks a lot for the link!

Updating plugins and restring IDEA worked for me. I am using mac 10.14.4.

I had the same issue upgrading from 2019.1 to 2019.2. My fix was to update all the recommended plugins by clicking the green bubble on the welcome window. After restarting this issue stopped. I am also MacOS

I've just updated to the latest version 2019.3 and the project list has been cleared (op system win10). I tried to update the plugins too but didn't help. Is there a way to import it somehow to get back?

I found the reference for my previous projects list (and groups) in the .IntelliJIdea2019.3\config\options\recentProjects.xml  so it seems it has been migrated from the previous version, but it seems idea ignores this.

UPDATE: I think the problem is that the recentProjects.xml   file has been renamed to recentProjectDirectories.xml
A workaround is to just replace the <option name="groups"> to the former one solves the problem.

Same with IdeaC 2020.1 and FindBugs plugin. Somehow it doesn't realize it's incompatible.

Mark Jeronimus

Thank you. We have marked the plugin as incompatible. 

However please note that it is a different case. No need to continue the thread about the macOS file chooser not opening projects.

Hello, I am experiencing this issue -- I am running MacOS 10.13.6. Previously, I could delete each project's .idea folder (which is a large pain), but now I have no idea folders left to delete and I still can't open IntelliJ (2019.2). It stops at the open window (the bar goes all the way to the end).  Please help, I am trying to finish my school project, thank you. 

I tried adding -Dide.mac.file.chooser.native=false to idea.vmoptions as it has been suggested somewhere, but that did not help. I only had one plugin (java tutor) and disabled it already.

Please report at https://youtrack.jetbrains.com/newIssue?project=IDEA with the logs, dumps and the screenshot of the issue.

See https://intellij-support.jetbrains.com/hc/articles/207241085 and https://intellij-support.jetbrains.com/hc/articles/206544899 .

Thank you for the quick response, I have reported the issue. I appreciate the help, as I really would like to be able to open IntelliJ again. Thanks!

I got the same problem since 11.3 Big Sur :( Can't open project which was opening before the update of this night. 

Please raise a new issue at https://youtrack.jetbrains.com/issues/IDEA and attach the IDE logs and a screenshot/screencast showing the problem.

See https://intellij-support.jetbrains.com/hc/en-us/articles/207241085 .

Thanks.
