Unable to receive Photos from my iPhone 13 Pro to MacBook Air via AirDrop

I cannot receive airdropped pictures anymore from my iphone 13pro. It used to work fine, now sudddenly stopped.

A few other weird things going on as well: people try to share albums and I don't get into them (No longer shared) And after each bakcup to external hard drive it says: Back up not complete since not connected to power despite me being connected to power.

I don't know if and how these issues are related though.

Any hints or tipss would be amazing!
