I have run into this weird thing starting yesterday. I am running my game on the github version of UE5.1. I double checked and made sure the project is set to the right engine dir, regenerated the VS project. Game builds fine, when I start game it says all the plugins were compiled in a different version of the engine! It asks if I want to compile them, it does and I can start the editor, but next time I compile in VS it does the same thing… I know its pointed to the correct engine folder
I rebuilt the engine, rebuilt the project, cleaned the project in VS and built agian… nothing fixes it.
Has anyone seen this? Know how to fix it?
As a note, this wasnt happening the day before. I did add a c++ class thru the tools menu in editor and it crashed trying to compile. I dont know if that was related or if its just coincidence

I had this exact issue happen to me. Did you solve this?
Did you try deleting the intermediate folder inside of your plugin? It might still hold old generated files from the previous version of the engine. Clearing and regenerating it with the newer version might clear up the errors.
You can also change the EngineVersion inside of uplugin if it has it, in newer versions it’s missing all together, so you can try editing it out.
