One or more blueprints has an unresolved compiler error, are you sure you want to Play in Editor?

I was trying to make a collision box to load a level and I did, it works, but now i have this error everytime I try to PIE.

It might have been because I force deleted an asset and it had a blueprint bound to it?

Help please, everything works fine, but I keep getting “One or more blueprints has an unresolved compiler error, are you sure you want to Play in Editor?
Level1”

I’ve tried restarting UE4 and even looked through all my blueprints, help?

[SOLVED] CLICK ON BLUEPRINTS AND THEN GO ON OPEN WORLD BLUEPRINTS
