I found the RasPi is sensitive to power supply issues and noise.
So I use a single 5V power supply soldered directly to the GPIO pins with a 100n cap on the supply lines
Even added a ferrite bead on the supply cable
Shielded and grounded the cable from the PI to the motor controller.
I also ensured the IMU HAT is solidly mounted on the PI header.
Not sure if this helps, but it does eliminate a potential issue.
