This seems to have started in buildid 20210907094849. One installation is responsible for almost all of the crashes but there's at least another user experiencing the same problem so this looks like a valid crash. Here's a bunch of URLs from the crash reports:

We should add the file name of the failing font to the panic message.

Depends on: 1730575
Flags: needinfo?(jmuizelaar)
Severity: S2 → S4

One of the crashes is failing with msyh.ttc which is Microsoft YaHei

Closing because no crashes reported for 12 weeks.
