I found the thread stuck when executing the following:
from PySide6 import QtWidgets from PySide6.QtUiTools import QUiLoader QtWidgets.QApplication([]) QUiLoader()
stack of the running thread:

And I noticed the program kept creating threads with the following stack:
0x0000000000000000 !NtWaitForAlertByThreadId+0x14 !TpWorkOnBehalfClearTicket+0x2c3 !RtlEnterCriticalSection+0x254 !RtlEnterCriticalSection+0x42 !RtlExitUserProcess+0x105 !RtlQueryProcessDebugInformation+0x3bc !RtlQueryProcessDebugInformation+0x1fb !RtlQueryProcessDebugInformation+0x11e !RtlpQueryProcessDebugInformationRemote+0x25 !BaseThreadInitThunk+0x1d !RtlUserThreadStart+0x28
I changed my code to the following and found all things work:
from PySide6 import QtWidgets from PySide6.QtUiTools import QUiLoader QUiLoader() # this goes first QtWidgets.QApplication([])
I didn't see any instructions that asked me to put this call first, so I created this issue.
