sure, our app is https://apps.apple.com/cr/app/cardiogram-heart-rate-monitor/id1000017994

we started facing this issue 2 version behind, where we did a rebranding and had to compile/generate a new build with latest xcode, had to update libraries and so on! before this, everything was working normally on every iOS! 3.7.21 was the latest working perfectly

crashes started 3.7.23! and again, the issues are more than 2k, but it's not really common to reproduce, my team and QA team has tried to reproduce it but no luck, but we have many users complaining about it, and analytics shows the errors indeed happening! 

this is another variant of the "same issue", and I say same issue because its happening in the very same line of our code, the stack trace is the one a bit different
