Opening any blueprint crashes ue4

Development Programming & Scripting

Hi everyone, I posted this yesterday but I put it in the wrong category. So I apologize for reposting it here…

So this just randomly happened to me. Last night I was able to edit blueprints in my project. Now when I open any blueprint in my project it just crashes. I can load into levels, place objects, and do everything else besides open blueprints. I did not recall make any changes to any of my blueprints (character level or game mode.) That I have seen people say that can be the cause of problems. All I did over the course of last night and today, was import Quixel assets through bridge, and edit the albedo of one of the meshes.

did you try to delete the intermediate and saved folders of your project?

3

Can I ask you to elaborate? (haven’t deleted anything yet.)

4

in your project folders, there are 2 folders called intermediate and saved, those contains build data made by the engine (everytime you save or compile) if you delete them, they will be rebuild on the next project opening, (don t hesitate to backup before you do)

OMG. Thank you very much, everything works again!
(Sorry for the late response I put the backup on my hard drive which took half a hour)
