This signature shows up much earlier, but started spiking in October. From April to now, there have been more than 22k crashes[1]. However, after about 400 to 500 crashes/month between April and July, frequency increased 4-fold to ~2100 in August, doubled again to ~3900 in September and then more than doubled again to ~9400 in October. November seems flat compared to October:

Apr: 405
May: 461
Jun: 562
Jul: 530
Aug: 2156
Sep: 3934
Oct: 9398
Nov: 7717 (up to the 21st)

With 7281 reports, 24.0 still is the version with the most crashes. 25.0 follows with 2601, 25.0.1 with 1127. Most of the 24.0 crashes (5560) happened in October[2], so the spike is probably caused by that version's adoption.

Having said all this, I see absolutely nothing in the signature that even remotely looks like it would explain the crash. :(
