Soft crash: Cannot read properties of null (reading 'userId')

Unknown: happened while trying to join a call

I've just reproduced this, and it appears to be a state desync: even though I'm joined, room.currentState.getStateEvents("m.room.member") doesn't include my own member state. In fact, it only shows 6 members when there are really 12 currently joined to the room.

It can't even see the m.room.create event :/
