Disabling Disregard for GC with an invalid asset in GameplayTagTableList causes a controlled crash

Disabling Disregard for GC leads to a crash in GarbageCollectionVerification.cpp VerifyObjectFlags. This crash occurs when there is an invalid path specified in GameplayTagTableList.

The cause of this issue appears to be that the Reachable flag is given to the object that failed to load in GarbageCollection.cpp OnDisregardForGCSetDisabled. Before the GC pass occurs, the value of Reachable is swapped with MaybeUnreachable in GarbageCollection.cpp FRealtimeGC::MarkObjectsAsUnreachable.

During GarbageCollectionVerification.cpp's VerifyObjectFlags, the object flags are checked, but the flags do not appear to be updated on the object, so the object fails the check and triggers a fatal log.

1. Create a project that uses Disregard GC
2. Add a bad path to GameplayTagTableList
3. Cook, then launch debugger as Development Server
