Advanced color stops working while shooting

I use Capture One Software to shoot artto work and use the advanced color editor to adjust single colors.

However, the entire color editor stopped working during my shoot yesterday, including the basic color editor, and I had to mask areas on the fly and use the white balance and other tools to help me finish the shoot. 

This has happened before–so prior to my shoot I deleted capture one and reinstalled it. At first it worked fine, but around painting #7, it stopped working altogether.

When I checked the session this morning, everything was working.

I have capture one 20. Yes, I understand capture one wants me to upgrade, but I'm in the middle of a career transition, and committing to a license for a program I use every few months is painful, given the price point and how rarely I use it and the fact I'm looking for work and dealing with inflation in all areas.

Here are my details:

Capture One 20 Pro
build 13.1.4.15

Macbook Pro, 16 inch, 2021 M1 Chip
OS 12.5

Thanks so much!!
