Intens and violent stuttering at low RPM - 75200 and QS205

Hey all! I have been working on an electric winch project, but am having issues with the motor starting from 0rpm. As soon as it turns it is super smooth, but the start is extremely violent and sketchy. I use a VX1 remote to control the motor using a flipsky 75200 and QS205 5T hub motor. Remote deadband is set to 3%, minimum ERPM is set to 10. Is there any way to smoothen out the start? I am not sure how to solve the isssue. The motor is set to hybrid sensored setting, and switches to sensorless only around ~200rpm

I use:
- QS205 5T hub motor
- 75200 VESC - 200A line 300A phase - Upgraded FW to vesc7.0 - no HW limits
- VX1 remote
- 72v 40AH 16KW battery

Any help towards a smooth start would be appreciated!
