Hi @AdrianSnigel,
Thanks for sharing your updates here. Based on what the expert mentioned in the latest reply, could you please try resetting your Illustrator preferences and then check if Offset Path and Compound Path appear again in Edit > Keyboard Shortcuts and work as expected? If they don't show up, please also try reassigning the shortcuts and see if they stay in place.
If the issue still comes back, let me know, and we can take this forward.
Looking forward to your update.
Abhishek
