I also experienced this crash while tapping on the several times"Sync now" button from the Synced Tabs and back grounding the app.

Hello, please note that we tried to reproduce this on the latest main and latest 9000 (13643) builds with iPhone 13 Pro Max (15.1.1) and iPhone 13 mini (15.5) but we couldn’t reproduce the crash anymore.

We tried with the exact steps we have but it looks like it’s fixed. I will mark this as done after testing the issue on a Release Candidate too.
