This looks like a regression in Fenix Nightly 107.0a1. The first crash report was from build ID 20220909093917, but I don't trust that 20220909093917 was the regressing build because there are a couple day gaps between early crash reports.

Set release status flags based on info from the regressing bug 1786584
