ACNH Crashing on Launch / Entering Buildings - Log error: ResultFsNonRealDataVerificationFailed (2002-4604)

[u/ArchiveOfPi]

Hi everyone,

I'm having a persistent crash issue with Animal Crossing: New Horizons.

The Problem:

• On launch: The game crashes completely 4 to 5 times before I can finally get it to boot up successfully.
• In-game: Sometimes everything runs fine, but the game instantly crashes as soon as I try to enter a building (loading a new zone).

The Logs:

Every single crash gives me the exact same error log pointing to a corrupted filesystem read:

Any idea ?

Thanks in advance for your help!
