Since ios15 was released, we got massive crashes on the Home page. it's not sure related to GCD or something else. and we difficult to reproduce this issue. the Home is the first page that will appear after spashscreen. Here is a sample stack crash at the top one.
Crash only on ios15
- 1 You're crashing on a background thread
- 2 This looks like it is calling a UI framework component that is meant for the main thread on the very same back thread inside a closure passed to the background thread.
