I have a strange problem running PhpStorm 2022.2.2 on Linux I cannot re-open existing project-dir. I already tried deleting the .idea-folder in the project dir, but even trying to create a new project from existing files doesn't open a new project-window! I already have two open projects but there's no additional window appearing and no message telling what's wrong as well.
Is there some cache/state file in ~/.PhpStorm2019.3/config/ which may be broken? I don't want to delete all my settings to start from scratch :-(
