App crashes when loading posts with comments

[d42ohpaz]

Describe the bug Scrolling the All feed, and tapping into posts.

Expected Behavior All posts comments load without crashing.

Actual Behavior The post content loads, but after a short delay the app may crash before it loads/displays the comments.

To Reproduce Nothing special. Tap into posts with comments.

Mlem Information: 2.0 (129)

Additional Context I use lemmy.world (0.19.3-6-g86e4cb214). I have also filed a couple of crash reports through TestFlight.

Some posts that I found that cause the crash:

• https://midwest.social/post/19172852 (0.19.5)
• https://slrpnk.net/post/15122292 (0.19.6)
• https://slrpnk.net/post/15122402 (0.19.6)

Also, revisiting the posts loads everything as expected. I've tried clearing the cache and restarting the app.

I possibly fixed this by adding an extra @MainActor in #1430; we'll see if it goes away once that's merged

So far so good with 138. I haven't had a crash all day.
