I had this crash twice yesterday, after not having it for a very long time. Here are two dump files and reports.

There you go.

Just had it happen again. Notice the fps dropped off a lot right before the crash.

Made two by accident.

Okay, the normal sprint works fine. The toggle doesn't. I set it to 2xW, and it just won't move, the character just stands still. I think the original issue has been fixed in a patch, I actually don't remember the bug.

Yes, but the toggle doesn't work for me for some reason.

a)Sprint is what I mean. It's called turbo in the controls.
b)For me, I use Wx2 for sprint. But when you do that, and run around, then stop, move again, and you will still be sprinting. Maybe it's supposed to be like that, but it seems like you should go back to normal pace after stopping.

Yep, this is in arrowhead too, but a lot more subtle. Just disable ATOC and all will be well.

This is a couple of years old, and I don't think the problem is around anymore.
