Good day. the project not open and give me an error.
How to start to debug?
Hey @ser.man94!
Looks like it’s likely an engine file issue. Start with doing this:
Open your Epic launcher and go to your Unreal Engine → Library tab, and use the dropdown on your version then run a file verification! 
Tried. it was first what i try
I found a long thread of people finding various fixes for this exact issue. Give them a try!
