How can I fix this seemingly corrupted project?

Upon reopening a project that was working perfectly fine, I get a strange visual distortion and weird behavior. All the gizmos appear flat, lighting is wrong, post-process effects are not working properly and objects on the map appear and disappear when selected. I don’t see any errors in the logs and tried rebuilding C++ code and lighting. I’m using Microsoft’s TF version control system and I’m suspecting it damaged something. Any clues where could I look into for fixing it? I’m attaching a screenshot that shows the player start and sphere reflection capture gizmos. Has anyone seen this before?

OK, found the problem. In case someone runs into something similar, accidentally NearClipPlane was set to 0 in the DefaultEngine.ini file and deleting this line fixed it:
