I’ve been attempting to compile my edits in the editor using live-coding, but I’ve been encountering these persistent errors.

I have tried rebuilding binaries, intermediate and DDC caches, as well complete reinstallation of the UE5.2 and VS2022.
In addition, I followed a suggestion to install the most recent Windows 10 SDK version, but unfortunately, this did not resolve the problem either.

Is there anything you would suggest that I should try?

Edit - I have removed the project’s path and name for privacy. They are perfectly valid names, with no spaces or illegal characters.

Most likely something preventing unreal from accessing files, it could be an anti virus or some file protective program.

I’ve already tried adding an exclusion in MS defender, it didn’t work.

I solved it by adding this to the module’s cpp file.

IMPLEMENT_PRIMARY_GAME_MODULE(FModule, Module, “ModuleName”);
