.uasset not getting loaded

Hello,

I worked on a game (surprisingly) and put my Laptop to sleep mode. I was not able to recover it from sleeping, but saved everything before putting it to sleep, so I shut it down. As I opened the project again, I noticed every file, which was open when I put the laptop into sleep mode, is missing. BUT the .uasset files are still there and they should not be corrupted, as I see no message. I already deleted the CachedAssetRegistry.bin, but I still don’t see those files loaded.
Even References are broken.

I hope you can help me to get back access to the files.

I am also having a similar problem. All of my files exist in the content folder of my project but when I open UE4, none of my files appear in the content browser
