thanks a lot for ur reply, I checked every now and then for answers but didnt think there will come an answer anymore :)
But in the meantime I switched from the binary install to the flatpak and couldnt be happier.. works pretty fine and always the newest version automatically :)
thank you anyway ...

Hello! I just installed MakeMKV via the steps that are provided here https://forum.makemkv.com/forum/viewtopic.php?f=3&t=224

Everything works fine so far, but can please somebody let me know the steps in terminal if I want to properly remove/uninstall MakeMKV one day?

How can I do that properly ...
