Put the complete resource folder under resources or a bracket category. The resource's fxmanifest.lua should be directly inside that resource folder.

Only when its documentation says that is supported. Exports, dependencies and code can refer to the original resource name.

That commonly points to start order or a dependency that was not ready during the cold boot.

You can ensure individual resources or bracket categories. Explicit lines are easier to reason about when start order matters.

Check for an extra nested folder and confirm fxmanifest.lua is inside the actual resource directory.
