Sprint bug

I Was playing the game the day before no problems but now that I play I can't sprint with a weapon out, have to have melee out or gadget to sprint. It's pretty frustrating because from my understanding of reading about it, this was an issue months ago that still haven't been resolved. Can you guys please do something about it because at the moment the game is unplayable for me and I'm sure I'm not the only one that has this problem
