The presence of a Last Exception Backtrace

Frames 20 through 9 are typical for block that’s been scheduled on the main queue. Frames 8 through 3 are ‘your’ code. Well, more likely code from your third-party tooling.
It’s hard to debug this further from the crash report. Your code has thrown an exception and it’s up to you to work out why. A good first step would be to symbolicate frames 8 through 3. See Adding identifiable symbol names to a crash report.
