Describe the bug / provide steps to reproduce it

It seems like the crash happens when there are 2 people inside a channel, and the leader and the other participant leave at the same time Zed will crash. I had this crash a couple of times already, so I think I can reproduce this easily.

More context:

• Most of the time the leader has their screen shared
• The other participant does not have their screen shared
• We only have 1 shared project

Having the same issue. It seems to correlate with someone disconnecting from the channel. There was no relevant info in the Zed log, however here is the crash report:
