Exceptions.ErrorOccurred()the culprit? Does it work if that whole section is put in ausing (Py.GIL)scope?It is the culprit. I'm unsure if it is totally advisable; PR incoming; grabbing the GIL only when embedded.
Just adding to this: we are seeing a similar segmentation fault while shutting down, only while debugging for same reason. Manually shutting down seems to avoid the seg fault QuantConnect/Lean#6439
Environment
Details
Using the Python for Unity package with at a commit hash later or equal to the one above, pythonnet causes a crash on Shutdown. I've traced the issue to this PR: #1780 which is cause by checking a Python internal without holding the GIL; which the shutdown process isn't doing (or at least not at this point).
