Danny.
I'm 99% sure that version has the changes that break out code.
Unfortunately I don't have a system that uses the new library so can't current test.
I have fixed the errors as best I can as they are reported.
I see errors from round_gauge in your post so will look at he code and see if I can fix it.
I pushed a fix for that particular error.
So you could try checking for linuxcnc updates.
I know no way to downgrade the pyqt version on the system.
Only by using an older distribution.
Ahh you used Debian debs to get linuxcnc. (I looked in the forum post)
Those debs don't automatically get updated.
I think you are falling in a deep rabbit hole here.
I unfortunately do not have a good suggestion for you.
