Hey there @Xernesser! Seems like the assertion that failed is checking to verify a class it’s accessing isn’t private.

Does this occur on any other projects?

Have you recently installed new C++ plugins?

That occur only on one project made in Blueprint
(for the second question : no )

Did you create any new blueprints recently, if so what do they do? It seems that one may be corrupted or targeting a class it cannot/should not be able to access. (Shouldn’t be possible in blueprint so it’s likely corruption/engine bug).

no i just reimport some texture because my material got corrupted

facing the same issue, how did you solve it? :melting_face:

for the moment i didn’t find how to solve it, I will try to reinstall Unreal engine and i will say you if that work
