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.
