constexpr redefinition errors when compiling Protocol Buffers generated code with Visual Studio 2022 and Protocol Buffers v29.3

[Matgo01]

I encountered multiple errors while compiling the code generated by Protocol Buffers v29.3 using Visual Studio 2022. The errors point to constexpr redefinition issues and other problems with functions being marked as constexpr. Below is the exact error message:
