Masking with a brush is slow to render or even recognize that I'm masking. Lots of beachballs

I've been editing some engagement photos off and on this past month. I was having zero issues making edits, using masks with lots of updates. I had to take a break for about two weeks and when I went back to doing the same thing I was doing before it was almost unusable. I would go to add/subtract from a mask and when I was done it would beachball for a few seconds then render. I would start again and it wouldn't even recognize that I had started again so I would have to wait again for several seconds and try again hoping it would work.

I've made sure LRC and Camera raw were up to date. I updated my OS to the latest version. I moved some content to an external to free up hard drive space. I updated the driver for my Wacom Intuos S. I increased the camera raw cache from 5 to 10GB and turned off "generate previews in parallel" as suggested by a post somewhere else. It still does the same thing.

So I figure I would try here since I haven't seen anyone posting with a mac with an M1 chip.
