Brrr. So from Unity 2021 LTS to 2022 LTS a .net target change took place, forcing our patching flow to move to .netstandard (from .netframework where it had been sitting due to Unity legacy).
Not the most hilarious of tasks, but stubbornly fixed now - ready for the next internal project on the "new" LTS :)
I'm mostly just glad there's no longer a development target platform factor in this whole mess, given our use of nix for dependencies (previously we pulled them from the Unity install).
