Cannot connect to already running IDE instance. Exception: Process 2 is still running

Guys, apparently this problem is solved by deleting the lock file.

There it more or less tells us where to find it. 

If, like me, you use ZorinOS, I recommend activating the view hidden files and then searching for the pycharm folder. 

Otherwise use this address in the terminal: ~/.var/app/com.jetbrains.PyCharm-Community/config/JetBrains/PyCharmCE2023.2$ 

I hope you find it useful
