Resolution Note:
Mono Backend's Managed Stripping Level is Disabled by default. IL2CPP does not have a disabled option and is Minimal by default. Types in use in asset bundles need to be specified to the player build pipeline via a Link.xml file or the assetBundleManifestPath parameter of the BuildPlayerOptions in order for the necessary runtime data to not be stripped from the player build. https://docs.unity3d.com/ScriptReference/BuildPlayerOptions-assetBundleManifestPath.html
This is all managed for you if you use the Addressables package to build and manage your asset bundles.
