Movement bug

About two days ago I started get a bug where my character will just stop moving forward until let go of the "W" key. Sometimes I have to let go for about a second or two before it starts working again.

It happens relatively random but certain things seem to trigger it most often, such as ADS or firing a weapon, pressing either "A" or "D" while walking forward, landing after gliding, and vaulting over objects. Don't what change caused this to happen but it's definitely just a Fortnite thing.
