Upload To Private Code causes an Error consistently.

Summary

Failure to create a private code on a project.

Launching session or matchmaking into private codes barely works (like <5% of the time) ever since the Dec. 11th update.
Now, since the Dec. 18th update, I can’t generate a private code either because it consistently throws the following error:
[DEP] valkyrie-source-content-live.s3.amazonaws.com returned unparsable JSON response SentryEventId=ec2a16ac96ea439295ee8b62d9754205
The event ID is different each time.
