Did you try to switch RHI 11 to 12 and vice verca ?
Does it happen on other project or only this one.

Try to update gpu driver to latest and delete your Intermediate, DerivedCache folders.

only happens with this project. i’ve update my drivers and nothing. i was working on the project earlier and closed it for maybe 2 hours and now it wont work outta nowhere

this might not work well but try to make another new project with the same name and same directory, then copy your content folder of old project to your new project.

i went into my DefaultEngine.ini and set my default map to nothing. it opens now so i think that map is screwed up. no idea how that happened considering i changed nothing

the map might have got corrupted during an autosave most likely, don’t forget to make some backup project :innocent:

thanks for the replies. yeah the whole thing is messed i guess. my game mode and player controller crash it now. well there goes that lol

not sure if this will apply, but if this is a source build then run it in debug mode from VS or whatever you are using, that way you will get a breakpoint and you can check the stack trace to see what’s going on

thanks, but i wouldn’t be able to do that since i cant even open my blueprint. it just crashes

i suggest making a new project, your current project seem corrupted sadly :frowning_face:
