Hi @seven415 can you share your Sentry options? Can you reproduce this locally with a minimal setup? And do you also see other ANR events on startup/initialization of your app? If something blocks the main thread extensively, the stack traces of reported ANRs might not be reliable.

related:
#3584
#3585
might have the same root cause, all happening during initialization

It cannot be reproduced locally. These ANRs are all seen from firebase.
