Urgent! Suddenly cannot open my project

Hi, today I cannot open my project that was working perfectly yesterday. When I try to open the project it goes to 54% and then its just closing without any error messages. I checked the log and it seems that somehow (very strangely) one streaming level became corrupted. When I delete the streaming level inside the project folder the projects opens without a problem but I cannot open the level that had the corrupted/deleted streaming level… All the backups from yesterday have this streaming level corrupt. I didnt notice this because I never closed the editor untill today (after restart). Please help, deadline is very soon.
Here is the log:

It seems others have had a similar issue. Here’s a thread I found that has an answer. This answer was for Mac, but the issue was hardware not software. Give it a look.

Thanks for the link, I am checking it now.

I am not sure if this is related to my problem (its more about packaging) but I noticed on the log that there is another error that I have missed which is: Memory cache was corrputed (size) C:…AppData/Local/UnrealEngine/4.13/DerivedDataCache/Boot.ddc. Is it possible that something went wrong with the RAM? Kinda strange because my backups should have worked… Its good that I have a backup which is a little bit earlier version that is outside my pc.
