Hi, I am a complete rookie in this programming stuff, but with a trial and error process and a lot of lucky, looks like I could solve a problem similar to yours.
Try this:
- Save in a .zip and remove the .dll file that gives you the problem (UE4Editor-Invert-2188.dll). I think it is located in folder “ProjectName”\Binaries\Win64
- Open the project with UE4 (in my case it opened with no errors).
- Compile in the UE4 editor.
- Close the project.
- Unzip the .dll file
- Re-open the project and check if it works properly.
I hope it works!
