Last what i did was make an array from images and compiled the bp. Then project crashed and now launching with this error

Hope this helps: Editor crash in change of using variable type in blueprint - Editor Scripting - Epic Developer Community Forums

Remove the file of the BP (should be .uasset files) you were working on

3

I know where the problem, but this bp is very valuable. Is there any way to edit this file without ue editor, or start the project with uncompiled bp?

4

that I don’t know.

You could try copying that file into another folder and try and get your project up and running. Then figure out how to get it back in.

Ok, thank you for answering

i got the same Problem, but when i go where the File with the error was, it’s just not there in my Files.
i tried restarting the Engine again but it still had the error.
Wtf,Epic?
