PS5, Couch Co-Op, Cannot Load Cruel Manor Ramparts

The wife and I are playing together. We zoned into Manor Ramparts the other night, hit the waypoint, and stopped for the night. The next day, we were hit by this "infinite load screen" error that I presume everyone else is talking about.

We thought we had a workaround when we had another character in the league that we could use with Couch Co-Op to get one of our characters to zone into Act 2 Normal, and then we both re-loaded into Act 1 Cruel.

We tried to then take the waypoint back to the Manor Ramparts, making sure to select "new instance." The loading screen is stuck for us there.

I've yet to try fighting through the executioner again, and we've yet to try Normal Manor Ramparts.
