Husqvarna YTA24V48 not stopping when foot comes off pedal

[vinmassaro]

Hello, I've had my YTA24V48 since about 2015 and recently an issue started where when I take my foot off the gas pedal, the mower continues to move. This happens in both forward and reverse and the only way to stop it is to use the brake. I am having trouble finding a video or details on what is causing this issue and how to fix it. Any help is appreciated, thanks.
