- Component version: 1.2.1_
[REQUIRED] Step 3: Describe the problem
App crashes (as detected by Crashlytics). Apparently while in garbage collection. I have a stack trace but it doesn't make much sense as it appears to be collection 0 garbage, and fails as operation not permitted on a file. The error and stack trace are likely the most useful items:
error:

I would love to have steps to reproduce but I haven't seen this locally, and don't have the logs or discussion of steps from relevant users / devices
Any instinct on how this could happen that could help me pinpoint it would be welcome
Relevant Code:
Unsure as this appears to be an internal routine. The relevant file appears to have last been edited by Grand Moff Harkin long ago and I'm not familiar enough with Firestore internals to make any guess as to possible modes of failure in a GC.
I may have missed them but I was similarly unable to find any open or closed issues in this repo that seemed relevant though I did try.
