Same as bug 1651702, this is most likely users with bad hardware.

¡Hola y'all!

Hope these lines find you well.

Crashed like https://crash-stats.mozilla.org/report/index/7015bcb4-ca60-42f4-8370-15a0e0210810#tab-details

Updating flags FWIW.

Let me know if y'all need anything from the profile or device.

¡Gracias!
