PyQt6 App crashes on windows due to stack buffer overrun
-
I have a simple python application using PyQt6 for a GUI framework that is packaged into an exe using pyinstaller.
The program runs fine on my development PC and a few production machines in Windows 10 Enterprise LTSC. However, on some production machines running Window 10 Enterprise 2016 LTSB the program crashes as soon as I make any calls to anything in QtCore like .isRunning() or start(). The windows error log has the following:
