So far I've updated from Photoshop 2020 to Photoshop 2021, reset the preferences file, and even uninstalled and reinstalled Photoshop... yet the problem persists.
My computer (PC) behaves normally until I open PS. Once I open PS my cursor gets stucks at the bottom right corner of my monitor (near the date and time). If I drag the mouse around I can get it to jitter around but it ultimately ends up staying stuck in the same place. Using Alt+Tab is the only way I can get out of photoshop and thus regain control of my mouse.
I feel like I've tried everything I could. Any ideas as to what this could be or what I could do about it?
