Cannot Access Hideout - Local Co-op PS5

My wife and I play local couch co-op on PS5, and recently we were randomly locked out of accessing our hideout after losing a Trial of Sekhemas. We were able to travel to other locations and the "Endgame" area, but not the hideout. The game kept saying something like, "You do not currently have access to this players area." Party settings and other in-game settings had not been changed or altered in any way that could affect this as far as I could tell.
