Movement Velocity Issue

Hey all, Ive been having this issue with my movement for like 2 weeks now and i have no idea how to fix it. The movement speed randomly changes to a speed that doesn’t match the servers it spazzes out. i have no idea why its doing this. i disconnect everything from my character but the movement and it still does it. so im stumped. Anyone else have this issue?

Heres a gif of the speed Numbers -
