This one started in 11.8 and has been becoming more prominent in 12.0 and 12.1.
It's currently the most common crash in Fabric.

Unluckily, the crash logs doesn't say much about where it occurs, but Fabric suggests that it is often seen when transferring bitmaps between Activities, or when saving a large amount of state between Activity configuration changes.

We had other occurrences of it in the past: #5456.

Also, this thread facebook/react-native#19458 suggests that it may be related to React-Native. The trend we see in Fabric (started in 11.8, growth a bit in 11.9, growth a lot in 12.0 and 12.1) seems to be compatible with mobile Gutenberg deployment in the app.
