Cannot deploy as rook from lobby error

Bungie Account Name - zeffer02#4137

Platform - Steam

Description of Issue - When selecting rook there is a lobby error that prevents me from deploying. It seems to happen after having selected a non-rook shell in trios mode. The error seems to be an issue with not being able to select solo mode which I would expect to have been automatically selected when a rook shell is used. It seems to be fixed by selecting a non-rook shell then choosing another mode (solo, duo,trios) from the currently selected mode. Then if you go back to selecting a rook and choose another mode it will then select solo and let you deploy.

Rough Date and Time of issue - 9:24 p.m. PDT (UTC-7) Thursday, June 4, 2026

Repro steps - video for reference. Video starts just after having closed and re-opened the game
