Before that, I compiled the project without errors, but after reinstalling Windows,
I transferred the backup of my project, worked in it for a while, decided to compile and
get this:

Hey @faker54321, welcome to the community!
When you re-installed Windows, did you also re-install the appropriate graphics drivers?
-Zen
Yes, I reinstalled the video card driver
I want to add that I also can’t do - “Zip up project”

Maybe it could be the starter content, or maybe the .NET Core? I can’t say I’ve seen that particular error before - My last resort would be to re-install Unreal.
I hope this can help,
-Zen
This probably happened through my fault, but I didn’t make a backup of a stable project, it looks like the project can’t be restored, I think unreal can’t find the path to important files.
Thanks for the answer
There is a plugin tha could help you, i used to get unknown build errors and that plugin saved my life. Let me just search and i will provide the link here.
Edit: Found it!
Give it a try, i think this will fix everything!
Problem solved. It turned out to be much easier. After reinstalling windows I can’t download visual studio
@faker54321, Glad it’s solved! Post again if you have any more issues!
Happy Developing!
