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. Solved in my Ubuntu by removing the pid process file:

rm -r /home/jlebrijo/.config/JetBrains/RubyMine2023.2/.lock
