Cursor from Magic Mouse 2 suddenly doesn't move horizontally

I didn't really do anything on my MacBook Pro (M1), besides implementing my work Mail account with the Mail app yesterday. However, everything still worked fine yesterday. But today somehow the cursor of my Magic Mouse 2 can only move vertically and can only barely move horizontally. I tried a few things to fix it: - turn the mouse off/on - reconnect - restart the MacBook - delete the files - reset bluetooth using *sudo pkill bluetoothd* in the terminal - delete the PLiST 3 files for the mouse in the library, as recommended here and then restart the Mac As I also have BetterTouchTool, I thought that there might be some problems related to it, so I turned it off. But the problem persists. Connecting the mouse to a different Mac made me realize that my mouse is perfectly fine. There's some problems with my Mac. What should I do?
