That’s not a VESC. It looks like a FSESC, based on VESC.
The gold thing is a resistor for current sensing. It definitely looks like you have a bad ESC. The question is whether a motor caused that or whether the ESC caused that.
I would disconnect the motors and do a hand test on each one.
Regardless of whether the motor caused the problem, your ESC needs repair. But if the motors test good then maybe try a new ESC. If one of the motors has an issue then maybe it might also cook another ESC, so if that’s the case I would try a new motor as well.
