👋 @dvdchr, I see your report on TestFlight:

Tapped a comment notification that goes into the comment threads. It loaded for a while; some comments are already visible. Crashed after a few seconds. Suspecting it was loading media, but would need to investigate more.

The stack trace for your crash looks very similar to the one described in this above issue. Both lack any function calls from the app, so it's hard to pinpoint where the issue might be.

Would you be able to search on Sentry if there's a Sentry issue for this crash, please? I couldn't find one based on your TestFlight email. Knowing this could help us assess how widespread this issue is.
