mozregression says bug 1983596.

Somehow submitting the crash doesn't show itself up in about:crashes.

The regressor is already backed out so maybe I can just wait for the next build? Affected people would need to update manually.

OS: Unspecified → Windows 11
Hardware: Unspecified → ARM64

I can confirm it, Win 10 Pro TB Daily 144.

One reason for failed crash submissions is the dump too large - 32k iirc.
