Dedicated Server Crash | LowLevelFatalError

Engine Version: 5.4 Source

When attempting to connect to my dedicated server, the server crashes. The container log shows the following error:

LowLevelFatalError [File:.\Runtime/CoreUObject/Private/Serialization/AsyncLoading.cpp] [Line: 3485]
Could not find SuperStruct PostTick to create PostTick
Signal 11 caught.
Malloc Size=262146 LargeMemoryPoolOffset=262162
5.4.4-0+UE5 1012 0
Disabling core dumps.
CommonUnixCrashHandler: Signal=11
Engine crash handling finished; re-raising signal 11 for the default handler. Good bye.
Segmentation fault (core dumped)

No clue how to fix it, saw some suggestions on google (such as turning off Use Event Driven Loader), but none of which seemed to resolve the issue upon repackaging the Server.
