UE5 crashing when opening any blueprint

Feedback & Requests

I’m still using using 4.27 for my project but have been trying to switch to UE5 as soon as the preview builds were proposed.
Everytime I start opening a blueprint, regardless of it’s size or importance in the project, it leads to a crash. I reported every crashes with the crash reporter in the hope of seeing the issue fixed in the next release but now we are at 5.1 and the issue persists.

I have installed the symbols in order to narrow the issue and it seems to come from the linker; last function called is FLinkerTables::GetImportPathName() in CoreObject.

Assets, materials and non scripted assets open fine. Does anyone know how to adress this as some features (nanite in particular) would be real game changers in my project.

Here is the latest crash trace I had with 5.1 prev2:

Edited to have some symbols in the body for search purpose:
