Hallo!

Is that Python3.9 installation the one which comes with the arm32 Raspbian?

If yes, you can:

• Attempt a fresh system install, try installing dependencies with system provided python with or without venv

If not:

• I assume that you might have built it yourself. In this case, try installing all of the packages recommended in this stack overflow thread, and then attempt re-compiling python* and then running the project again using the new build.

Also, as a last measure, you could try stripping out the python3.8+-dependant pieces of code from the project.

I think that the only thing I use from that is fstrings with =, but I'm entirely unsure about the dependencies, so no guarantees this could work as I haven't tested it.

I removed all code dependant on python3.8 and newer from 5c39b9c for now.

Tested it - works with my install of python3.7 for now.

Won't claim support officially, as I don't guarantee that this support will stay in case it comes in a way of implementing new features.
