This might be due to the Unity version SR2 uses. There's a couple of 2021.2 subversions that have their exe files incorrectly labelled as 2022.1, which triggers CPP2IL to try to read the metadata as V29.1 instead of V29. With that said, I believe you mentioned in discord that this doesn't happen in the development branch (the pre-releases) and I don't think the code has changed.

You can try using the --force- options (use --help to list them) and manually specify the correct unity version, and see if this helps?

On nightly it works
