If I had done this before looking high and low all over the internet, I would have read:
Updated on 2020-12-24: GIMP 2.10.22 DMG revision 1
GIMP 2.10.22 build for macOS - has known performance issues on Big Sur
and looking more into it, I found that these "known performance issues" include the fuzzy select tool not staying selected. Unfortunately, there isn't anything I can do now until this is fixed besides downgrade my operating system.
I'm hoping it's fixed soon. But it might happen to you sometime in the future, so I'm adding it here for one more thing to be aware of.
Thanks for posting this - I have the same issue and thought I was going insane!
