Hi all,
I had a unexpected crash when working on a blueprint. ( 5 EA2)
This is from the crash report:
Assertion failed: false
[File:D:/build/++UE5/Sync/Engine/Source/Runtime/Core/Private/UObject/UnrealNames.cpp]

It seems to me that I have to remove a certain node (MaterialInstanceDynamic-node to be precise) in order to get it working again?
But how do I do that?
Is it this one:
File:D:/build/++UE5/Sync/Engine/Source/Runtime/Core/Private/UObject/UnrealNames.cpp
It looks like it is too long on one line?
[Line: 2007] FName’s 1023 max length exceeded.
Got 3683 characters…
So can I go in an delete a bunch of data from that line?
How can a Project write data into a Engine source file? I thought all data was kept in the project-folder?
Or I could enable long filename support in my project… But how can I enable it when the project crashes? Any other file to edit?
I hope someone can help me out 
Thanks in advance.
