How this could possibly work?

It's hard to say for sure, as there are so many of them. The app in question was in the "Per-App Settings" (I think I tested font sizes and dark mode), plus I had accessibility shortcut for color filters. Removed everything, reset VoiceOver, but I didn't see any effect, it's still 7-8 seconds of initial sluggishness. We do have a lot of libraries, 81 packaged dependencies, 17 of them are local.

Hi Quinn! Several devices with 18.6.2 and 26.0.1 were NOT crashing. The only two devices that were crashing were 18.1 and 18.3.1

Any updates on this issue?

Doesn't work for me. I don't use tabs at all.
