Invalid native call in resource (game fatally closing)

What causes it

The client crashed because a resource invoked a native incorrectly — wrong argument types/counts, or an issue tied to the fxv2 OAL (optimized argument lists) experimental flag on certain builds. Frequently seen after enabling experimental flags or on mismatched client/artifact versions.

How to fix it

Fix the offending native call and avoid experimental OAL flags unless you know a resource needs them.

1. Note which resource is named in the crash; disable it to confirm it's the culprit.
2. Remove any use_experimental_fxv2_oal / OAL flags you set unless the resource explicitly requires them.
3. Check the resource passes correct argument types to natives (a common cause is a nil or wrong-typed arg).
4. Update to current recommended artifacts and a matching client build.
5. If it's a third-party resource, report it to the author with the crash dump.
