Maybe antivirus counts .uproject file like infected and gets rid of it. Try to download again but without active antivirus. I have same problem few times. Or computer don't have some .dll files

I download the missing dll files and put them in the correct system folder but I still get the same crash log error.
I think the problem is with how unreal engine is interacting with my computer. I'm not saying the problem is with your game but the unreal engine itself. Other people are having the same problems as me across the internet from other unreal engine related topics.
