Fatal Error TerracottaGuardian

Sorry for the terrible screenshot, but I thought I captured the entire screen too but it didn't save.
I'm using DX12, the map was Hidden Grotto, I'm not sure if it was T15 but it was an high tier for sure, I wasn't alone crashing.



The crash happened a around 10 minutes ago, EU Servers, playing multiplayer and I was NOT hosting.
