I’m getting the following error when trying to generate project files for my 5.0.3 C++ project:

I can generate 5.03 project files without any issues. This only happens with 5.1. I am using VS Community 2022. Windows 10.
Also happens when creating a new blank 5.1 C++ project. Getting the same error.
Any idea what might be causing this issue?
Thanks!
