I recieved this error when trying to open an Unreal 4.24 project in Unreal 5.1. Any debugging tips on how to open the newer version of this project up?
Hi Maddriddle,
What’s strange is that I’ve never seen that error when opening a project, only when trying to package or zip a project… It’s the same error, so try installing .NET
Good luck!

It also happened to me yesterday, after formatting my C drive. I can confirm .NET Core 3.1 fixed the issue (for me)!
