Any solutions to this problem?

Thanks in advance for your help!

Same error for me. I don’t know how to fix it, but by looking at the error, we can see the flag -WarningsAsErrors , may be we should turn it off, but how?

I finally got it to work. I removed my Visual Studio 2019 installation, upgraded my VS 2017 installation to the latest release, tried again from scratch ( I re-downloaded everything) to build the engine in the latest version (4.24.2), and I had to update my project to this new engine version but now it works!

I hope it will help you!

I generated the MSB3075 error by leaving the UFUNCTION() macro in an override function. I tested a couple times to make sure this is what was generating the error. I would suggest checking your functions before taking more drastic actions.
In Parent.h:
UFUNCTION(BlueprintCallable)
virtual void BuildGameObject(FName ObjectID);

In Child.h:
UFUNCTION(BlueprintCallable)
virtual void BuildGameObject(FName ObjectID); Generates MSB3075 Error

            virtual void BuildGameObject(FName ObjectID); **No Error Generated.**
