The host of the game doesn't have the text issue, while all joining players do.
The problem doesn't occur if the player is the host, only if they're joining the server.
We've all restarted our games, verified local files, and rejoined the same server.
The issue doesn't happen on any other mission, only the Depths challenge.
Nobody on our crew is using translation packs.
Two players are using Win10, I am using Win11.
