Magic Mouse oddly sensitive

Hi, 

This is my first time posting here so please forgive any weird formatting or missing information. 

Since this morning I'm experiencing weird sensitivity issues with my Magic Mouse. My screen keeps jumping around and just resting my finger on it triggers movement. Which made working with shortcuts a nightmare. The second my finger rests on the mouse a second after I released the click it moves, which makes it hard when using shift or option.

The mouse is still quite new, I bought it in June, and I haven't had any issues like that since this morning. Full disclosure the mouse was dropped this morning but the issue only affects Illustrator and InDesign. Photoshop and my browser are not affected. 

I assumed it might be an issue similar to the issue in Illustrator v 26.4.1 where it blocks you from moving an object and a little green circle with a plus pops up. However, through a different thread, I found the solution to that being going back to an older version. I was hopeful that would resolve my mouse issues as well, but alas I'm still struggling with it.

I turned off the scrolling option in both Illustrator and on my MacBook, but I still need scrolling for other things. So I'm hoping there might be a different solution to it. Did anyone experience this as well?
