Editor crashes every time I'm trying to edit second blueprint

Development Programming & Scripting Blueprint

The engine crashes every time when I’m trying to access any second in a row blueprint editor.

I can create any blueprint, open and edit it in a blueprint editor without any problem. But the moment I’m trying to open blueprint editor for another one - it crashes.

It happens in any project, old or new, blank or template.

Only one time it sent me a report after a crash. Here it is:

can you Verify the Editor/Engine install? (if you got the Engine from the Epic Games Launcher then open the drop down arrow for the given Engine install and select “Verify”)

what Engine version are you encountering this with?

what is the hardware of the system encountering this issue?

what are the fewest steps that you can perform that make this crash happen?

in the [ProjectName]/Saved/Logs/[PojectName].Log what is the last 20-30 lines of that file.

(I would suggest you do not share the Id values openly except with Epic, as they are directly identifiable)
