Intellij cannot launch because 'process 2' already running
Answered
After using intellij for multiple years on the same pc without any problum, suddenly this happened. When I want to startup my intellij on Ubuntu I get an error: "IDE Already Running", Cannot connect to already running IDE instance. CannotActivateException: Process 2 is still running. When I press "V ok" intellij starts up, opens, and then closes immediatly. I've tried restarting my pc and reinstalling intellij. When I check my running processes, nothing that has anything to do with intelijj is running.

Remove the .lock file
.config/JetBrains/IdeaIC2023.2/.lock
I was able to solve this by deleting
~/.var/app/com.jetbrains.DataGrip/config/JetBrains/DataGrip2023.2/.lockfile.It may be in a different location on your system, so try searching for
.lockfile in your home folder.In my Mac there is a file named .lock in ~/Library/Application Support/JetBrains/IntelliJIdea2023.2 folder, the contents of the file is the unix process id of the running idea instance. When the computer is chrashing while idea is running, this file will not be deleted after reboot, so idea will not start. I manually deleted this file and everything went back to normal.
I have same issue on macOS sonoma. my webstorm 2023.2.4 install from toolbox. cannot launch.
Issue should be fixed in 2023.2.5 and 2023.3: https://youtrack.jetbrains.com/issue/IDEA-330531
