The op amp is used as a constant current source to drive the stepper motor to generate oscillations. How to modify the circuit diagram?

A constant current source is used to drive a stepping motor. When the DRV_SIN input voltage is 0V, it is normal without load. However, if the motor is added, some will oscillate, and some will not oscillate. I always feel this The circuit is weird, is there any guidance from a great god?

How about moving R79 and C99 to both ends of the motor? C99 can be enlarged
