It is not possible to work in one instance of Webstorm while another is opening

I am not sure when it has started but the parallel work is not possible anymore.

When an instance of Webstorm is opening the rest of windows of it are hanging and it can take quite long time.

Could you clarify what you mean by multiple instances? Multiple projects in separate windows? Several IDE versions started at the same time?

Running multiple instances of the same IDE version had never been supported


Sorry, I meant multiple projects in separate windows.


Do you mean that the IDE stops responding when you open another project in a new window, or? Please share your log folder zipped (Help | Collect Logs and Diagnostic Data)


Yes, I mean exactly that.

I can not attach zip files to the comment. It allows to pick only (jpeg, gif or png)

You can find logs on Google Drive



does the issue persist if you disable/un-install nx-webstorm ( plugin?
