Photoshop 2021 is making my computer slow

I can't remember how recently exactly it started, maybe as soon as I updated my mac os for Catalina back in November or December last year? Or maybe since I installed Ps 2021, or perhaps very recently when Ps 2021 got updated this month; or perhaps even when I sdecided to sync my downloaded brush presets so I can use them on any computer. Needless to say for the past ten days as far as I can recall my my photoshop has been progressively getting slower and slower, and anytime I open it it lags my whole computer.

Any other adobe product works just fine, but Photoshop specifically seems to cause my computer to lag or even crash and I don't know why.

I'm inclined to believe it has something either to do with the Catalina or the recent program update but I don't know for certain.

I wanna say maybe I'm due for a new desktop, I mean I had it for well over five years already after all, but that said it still seems to be okay except for my photoshop.
