@eskimo here's a crash report, app name redacted with "OurAppName". Sorry this is only the Sentry crash report, so some information may be missing that would be included with an apple report. Maybe somebody else in this thread or OP could provide a full apple crash report? I don't have access to them.
We're experiencing the same thing, a big amount of these types of crashes and we don't know where we're even supposed to start with them.
