Sticks key races (Assassin's Creed: Odyssey)

For a long time played, reached LVL 17. Suddenly realized that the character is behaving strangely, not lariguet on the keys, live their lives KRC. Later realized that what the movement button is not press, he will be running in the wrong direction for a few seconds.

With fps everything is fine, no problem. I play on PC, so the keyboard cannot be hot. checked the control settings, there also seems all right. I looked on different sites and forums, nowhere sane answers could not be found, only noticed that with Ubisoft games, it happens.
Thanks for the help.
