[bug] App crashes silently on windows when trying to leave only one participant visible

[mateuszfilipek2000]

Describe the bug
App crashes when trying to leave only one participant visible on the screen (by clicking on the participant). The only OS we've experienced the issue on is Windows, macOS and web work fine.
The crashes are silent, no error is thrown in the console, crashes are not picked up by sentry, the app just closes without any error message.

To Reproduce
Open: https://github.com/mateuszfilipek2000/livekit-crash-test/tree/main (which is just a slightly modified example from your repo, with grid and on tap action added on participants, everything else is the same) with few participants in the room (I've tested with the amount of participants ranging from 6 to 40), click on one of the participants name labels to leave only one participant visible on the screen. The app should crash. Sometimes it takes few tries to crash the app, sometimes it crashes on the first try.

Expected behavior
The app should not crash, if the app crashes it should throw an error message or at least be picked up by sentry or other error tracking software.

Platform information
The crash happens on Windows 10 and Windows 11, I've tested it on multiple windows machines and it always crashes. Specs of machine on video: Lenovo ThinkPad t14, i7-10510U, 16GB RAM, Windows 10 Pro 21H2

hey @mateuszfilipek2000 , can you try this branch #370?

[mateuszfilipek2000]

Hi, thank you for your quick response. I've checked out the version you have provided, and after a quick bit of testing it both on Windows 11 and Windows 10, it seems like the problem is solved; the app no longer crashes. We will be testing it more thoroughly after the new version is released; if anything comes up, I will let you know. Thank you for your help and for the great package!
