I am guessing that you are building from git master?

Any of these solutions should work:
* specifying "--sync-xvfb=0"
* building a stable version instead of git master
* "git pull" and install again

No. There are no compatibility problems with any actively supported 
Python versions (from 3.6 to 3.11 inclusive) though you may need a fully 
up to date toolchain for Python 3.11

Yes, install xpra at both ends.
(you may skip installing the client if you use the html5 client instead)

Assuming that you want to run a seamless server ("xpra start") then this 
session will automatically start an X11 server for you to host the 
application you want to run. (ie: xterm)

On the client side, you can run any window manager / desktop environment 
you like, including Wayland. (though some features are not available 
with Wayland clients)
