Summary
Internal Cooker Error, it’s on our Project Operation Infiltration (OI) and it appeared 3 days ago and it’s not allowing any session to be made and worked in.
We have seen “Internal Cooker Errors” before on update days but they go away but this one seems random and it’s still here after 3 days. No clue on a fix so just wanted to forward this in here. (We attempted: Validation Fix, Different Accounts, New Versions and Restores)
