Following modules are missing or built with a different engine version (4.26)

My UE4 4.26 project (PuzzleGame) is throwing me an error when I try to launch it after the editor crashed on a C++ class error. I have since fixed the C++ class error.

The error reads:
*The following modules are missing or built with a different engine version: *
PuzzleGame
Would you like to rebuild them now?

I have been reviewing several posts about this issue and they all seem to point to an issue with the source not compiling, however I am able to rebuild my projects source (after generating new source files and deleting the old folders) in VS2019 no problem. It succeeds every time and when I run the .uproject file it asks the same question if I would like to rebuild. If I select “Yes”, it attempts to compile and eventually says:

PuzzleGame could not be compiled. Try rebuilding from source manually.

Things I have tried:
Deleting folders (.vs, intermediate, saved)
Deleting solution file (PuzzleGame.sln)
Rebuilding project solution and always succeeding.
Turning plugins off in .uproject file

Any help would be appreciated!

Have you found an answer to this? I’m new also and want to do the same thing to mine.

I need help with this too!
