FOC motor just grinds on speed command, spins up smoothly during parameter calibration

I'm struggling to run a brushless motor via my VESC 4.12 controller in speed control, however, this was all working fine a few months ago. Now, when I command a speed via vesc tool GUI, the motor just grinds and I get the current/RPM sensor data linked below. When I tried to update the FOC parameters, during the process, the motor is spun up beautifully with no problem. Can someone explain how that might be, and/or help me figure out how to get speed control working again on my controller?

Does it spin when you use the keyboard control? Do you use the latest VESC-Tool and firmware?
