Managed to get some info from windows event log. Have no clue why - seems the more static controls I create, the higher the likelihood of this happening is.

crash is caused by the WndProc definitions, seems having python code that does anything inside of those WINFUNCTYPE ctypes callbacks increasing the frequency of the python crash with positive correlation to amount of python code in the function.

Please provide code which consistently causes the crash, otherwise your use of ctypes makes the very likely not Python's fault and nearly impossible to debug without a working example.

Closing as there isn't enough information here for us to do anything about this. Also, Python 3.7 is no longer in maintenance. If you are still having this problem with a current version (>= 3.9) please create a new issue with information on how we can reproduce the problem.
