JF Arrow - Random aileron inputs?

I’ve been using the Arrow for a couple of weeks with no issues. Suddenly, starting Monday May 17, I started getting random aileron inputs. It mostly tried to roll to the right, but sometimes it will drift left. If you let the joystick go, it rolls over within a few seconds. These inputs overcome the autopilot.

I changed nothing. Nothing updated, nothing changed. Flew the plane a couple hours on Sunday with zero problems.

All other MSFS aircraft work normally, as well as the pitch and yaw axiis on the Arrow. Only roll is affected. This happens both in the air and on the ground, engine on and off. No issues with any other aircraft, or games. Only the JF Arrow.

My joystick in a Brunner CLS-E stick FFB, using vJoy to interface with MSFS. I have no idea how to troubleshoot this. I was running the v5.0 version of the arrow when this started, I updated to the v5.2 version with the same results.
