So I had TorqueBoard vesc for a while absolutely no complain. Then I saw the new VESC TOOL and I update the firmware according to the program suggested. Go through all the configuration and getting to the FOC setting tab, I click the lamba button to make the motor run but instead of running I heard a loud pop. Felt the vesc and it’s pretty hot. Burn residue around the IRFS mosfet thingy close to the red wire… 
My plan as of right now is checking whether if the mosfet is burn or anything is burn so I can replace it. If anyone can guide me, I would really appreciate it.
