I thought I had a fix but no.
The bug is still there: Mint 21 / Gimp 2.10.32 from PPA using MATE DE
FG/BG color picker reverts to whatever tool is active. Colour picker tool works (but of course does not pick from the outside the open image)
Changing DE to cinnamon and FG/BG picker works as expected
edit: So far the only work-around I can think of is using the screen capture tool File -> Create -> Screenshot That will open a selected area as an image and you can color pick that.
something like this: https://i.imgur.com/4QTyMtL.mp4 ctrl to use paint/pencil as the picker
edit again: Tried the fix mentioned in the bug report uninstalling xdg-desktop-portal and xdg-desktop-portal-gtk and that works (providing it does not scramble something in your installation and is applicable to a flatpak)
