What is not clear from the threads history is, which exact versions you used on the various systems.
On sourceforge we provide one 2.1.3 package and two 2.2.0rc2 packages for macOS.
The 2.2.0rc2-BigSur package was built from a community member, because the first 2.2.0rc2 package (built on HighSierra iirc) didn't run on Big Sur.
We got several reports about errors with the first 2.2.0rc2 package on Big Sur and also multiple positive reports that the 2.2.0rc2-BigSur package runs well on Big Sur.
But the errors were about freezing or crashing application, not such weird behavior you reported.

So can you clarify this and post which packages you used. Did you use our sourceforge packages or possibly from some other download source?
Or did you even build from source code?
