I found the problem, it’s a blueprint of a door that I was configuring… I managed to change in the project configuration to start the project in the game menu… but I can’t edit the blueprint to fix this, I click on it and the unreal engine closes, does anyone know how I can get around this?

Problem solved! Since I found out what was causing the error, I went to the content in my window explorer… I found the asset… I took another door with similar code from which a duplicate had been made for this one… and replaced the one that had failed with one new copy… the project is working correctly again!

do you know what the problem with the blueprint was?

I am getting this same address error related to my game mode on two separate occasions, but I don’t know what is causing it because I cannot open the blueprint

When the blueprint error occurred, I was editing a code to be able to open a door only if I already have the specific key, if I’m not mistaken I left a poorly configured branch in the door blueprint and had restarted the software
