Thanks for creating this issue, I de-symbolized the stacktrace and it is related to the List V2 block:

Issue reported on WPAndroid in Sentry; not sure if it applies to WPiOS as well or just Android.

I checked and it happens on both platforms.

There is a fix already for this bug so we will include it in Gutenberg mobile as well.
