This was seen on nearly every nightly up until build 20200201092806, and then stopped completely. Seems safe to say that the crash is gone.

(There was one hit in build 20200207195153 but it had a different reason code and different stack, so I would call that a different crash that happened to fall into the same signature bucket.)
