Not sure what to make of this but the crashes seem consistent across multiple reports so it seems like a valid issue. Many of the nightly crashes appear to be on Facebook.

in the last 6 months there are essentially no beta or nightly crashes.
in the last 6 months No significant change in crash rate IMO https://crash-stats.mozilla.org/signature/?product=Firefox&signature=hsw%3A%3Alowp%3A%3Abilerp_clamp_8888&date=%3E%3D2021-09-05T15%3A13%3A00.000Z&date=%3C2022-03-05T15%3A13%3A00.000Z#graphs

No, looking at the few recent crashes there's a significant chance that they're being caused by flaky hardware (many have triggered our bit-flip detection logic). Zooming out looking at similar signatures with a larger volume - such as [@ hsw::lowp::gather] this pattern holds: most crashes are probably caused by bad memory. So this was likely a flaky-hardware issue all along.
