I think this report matches your description more or less.

https://bugreports.qt.io/browse/QTBUG-75552

Have you tried other versions of PyQt5? If the report properly 
identifies Qt 5.12.3 as the affected version then PyQt5<=5.12.1 should 
work.  But, if it doesn't, maybe try a few more versions back.
