That environment variable is only relevant when building PySide6.
I've not had much experience with a Sigil plugin Python environment that includes packages installed to a user site directory instead of the system one. Can you show me what the test p!gain shows for sys.path locations? It should be some of the very first output when running the testplugin.
The fact that Debian/Ubuntu doesn't yet supply their own PySide6 packages (to be installed via apt-get) is unfortunate. Problems like yours are not likely to go away until they do.
One quick thing to try is to skip the sigil launch script in /usr/local/bin and launch sigil directly from a command prompt using:
/usr/local/lib/sigil/sigil
If Sigil starts ok, try running the test plugin again.
