help please unreal all of a sudden wont let me save my project

I was working on my project when Unreal Engine crashed, displaying a memory warning. After reopening the program, I noticed that some textures had disappeared from my objects. I attempted to reconnect those textures, but the project wouldn’t save and indicated that the files might be corrupted. I tried resaving the assets and texture maps and re-importing them, but I still couldn’t save my work. I also checked the permissions, and everyone has access. I’m really at a loss here. I’ve been working on this for months, and it’s incredibly frustrating to face this issue right before my deadline.
I’ve observed that some of my glass appears green now, and all the textures in my Maya project have disappeared


. I’m not sure if this is connected, but it all happened around the same time.
