Comment 4 for bug 1947138

I think cherry-picking https://github.com/python/cpython/commit/097801844c99ea3916bebe1cc761257ea7083d34 would probably fix this, which we could do in an SRU to Focal. There might be an easier workaround I can manage in the code. Or I could try to switch the git-ubuntu snap to core22, but that'd be quite a bit of work.
