UPBGE 0.36.1 Crashes upon switching to a particular scene. (Revisit)

[Shadestuff]

Late September of 2024 I encountered a crash upon attempting to enter select/enter a scene, or even interacting with means of viewing or modifying the bugged scene. I wrote it up as an issue here and was very kindly asked for more info/files to replicate and test it, but I was discouraged enough from the project that I shelved it, and never responded. -> #1913 (I'm sorry Youle!)

I've recently appended my assets back into a new save and have been rebuilding the project, and the same problem quickly returned. This time I've prepared a packaged file for replication. All it takes for me to crash UPBGE is to load the save and swap the scene to "Assets". Entering the "Blender File" Library to troubleshoot what objects or items may be causing the crash in the effected scene also causes a crash. Seemingly any in-program poking of the effected scene will cause a crash. Notably, where the crash log listed "EXCEPTION_ACCESS_VIOLATION" in the prior Issue's Debug Output, this new appended-rebuild file's Debug Output lists "EXCEPTION_STACK_OVERFLOW" (Along with a "Pip" update and instructions I'm not smart enough to follow.)

Blend: SEWN_GAME_packaged.zip
Debug Output: blender_debug_output.txt
Debug System Info on request, if need be.

I'm an artist first, trying to see how far I can go with UPBGE. Still not quite literate with code or using Github either, so much thanks in advance for your patience if I've built the ticket or attached files incorrectly.

I had a quick look and it seems an issue on Blender side. There is a depsgraph dependancy cycle detected, which concerns an Object in your "Assets" Scene (RockWall).

I will ask Blender developers if they want to have a look at the file and fix it in next versions of Blender, then if there is a fix, it will also be fixed in upbge last master (last development version of upbge).

BUT old versions won't be fixed.

I will try to remove the problematic object and give you a new file without it

Thank you very much! That's interesting to hear, I'll do some troubleshooting on a new save to see if I can replicate it from scratch to avoid it until patch/going forwards. I'm likely poorly executing how I handle object naming and linking between scenes used as game-levels.

I tried to recover your file but I didn't manage to remove problematic scene/object.

I will report file to blender developers when i'll have time and will tell you if/when they have fix

Well, Campbell Barton had a look at the file and said that there is nothing we can do with (as we don't know the steps which lead to file corruption), then I close the report, sorry that we can do nothing

[Shadestuff]

I'll continue troubleshooting, Thank you.
