Character started moving on its own

Xbox (SeriesS)

In a ranked match, both teammates quit, im 4 kills up and in a fight my character (wraith)  just starts walking sideways on its own, absolutely nothing on my controller worked to stop this, not a drift, like no buttons on my controller responded. I had to take the batteries out and put them back in to get it to stop as i was running into the 3rd storm! It was a close one! Was too busy trying not to die from  the huge final fight to record ;_; 

Idk if anyone else has experienced this but it was scaaaaaary
