Semi-random one-time Blueprint crashes

Sometimes when I rename something, like a blueprint interface function, Unreal crashes.

Then, when I open the project, it crashes again.

The third time, everything works fine. I can rename it again and Unreal acts as if nothing has happened.

It’s not a big thing, but it has happened enough over the years (I began in 4.22 and still does in 5.2.1) that I’m now making a thread about it.

Not a crash, but also related to the re-naming of a Blueprint interface… the functions just silently began failing… so then I removed everything but the content and config folders from the project, let it re-start and then it worked again.

Together with the issues when it comes to de-bugging Blueprints, they don’t seem very stable.
