I've also had this problem with the flameshot icon disappearing after upgrading to 20.04.
Reverting to gnome-shell-extension-appindicator 33-1 has fixed it for now, but having broken dependencies isn't good (even if things seem to be working).
Comments on https://github.com/flameshot-org/flameshot/issues/1206 also suggest this problem doesn't occur with the flameshot snap. Testing the deb package specifically may be a good idea.
