Please i need help with this

I tried running pycharm after installation and I kept getting the below. Please how do i resolve it?

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

This seems to be a problem with IntelliJ applications (on which PyCharm is based) & most likely not Flatpak specific. Unfortunately it appears randomly & the cause wasn’t identified, yet.

There is a workaround to get the application running again:

For PyCharm the file is in another location: ~/.var/app/com.jetbrains.PyCharm-<Community|Professional>/config/JetBrains/<current version>/.lock .
You’ll have to adapt the path for your version (Community or Professional & the current release).
