Cannot use Hideout (PS5)

I found a hideout in the Atlas (Limestone Hideout).

I selected the hideout with Alva, and it said "loading", but didn't actually load.

I tried the waypoint, it just offers the "select" dialog, with no result.

Using /hideout gives the "loading" message but errors with "Failed to join any instance".
