Failed to resolve validation session

Summary

At approximately 10-11pm ET on March 1, we became unable to launch sessions in UEFN. After launching a session, the bar gets stuck at “Validating uploaded content” for 5-10 minutes and then eventually lands on the error ‘Failed to resolve validation session’. Around this time yesterday, this was happening on multiple maps. Since then, it has resolved on some maps - but we are still encountering the error on our large open-world map (3469-7377-0976), preventing on pushing a critical update.

We have tested this across multiple snapshots, including snapshots from last week that definitely worked and are the current live version that players are playing. Across all snapshots, this error persists.
