Assertation failed: Offset <= MaxOffset

I have a project which up until last night was working flawlessly- today I opened it up for less than 5 mins to show to a colleague and it crashed with the following error

Assertion failed: Offset <= MaxOffset [File:D:\build++UE5\Sync\Engine\Source\Runtime\CoreUObject\Public\Serialization\BulkData.h] [Line: 395]

I am now unable to open the project. To my knowledge I did not do anything besides open a few Media Players, not even save. I have tried deleting DerivedDataCache, and verifying the engine files, no luck.

I have gone to the BulkData.h the assertation references, but am not seeing anything I can make sense of (just an artist lol), it does refer to Offset however

I have attached the BulkData.h file if anyone would be willing to take a look and offer a possible solution, would be very appreciated! :slight_smile:
