Bug: Pressing the a key makes it go to the top of a score Musescore 4

Hi, this is my first time using the forum (or any forum actually) so sorry if I miss some forum etiquette or something.

Any time that I press "a" on my keyboard the selection thing just immediately goes back to the start of the piece, so I have to avoid using the note a (which is a real pain, as A minor is one of my favourite keys). I didn't have this issue with Musescore 3, so I figured it was a version 4 glitch.

Would love if there was any solutions!
