I would pull the motors out of their mounts and make sure they are all spinning the correct way. As Al said, it sounds like an over current issue. I have seen it where one of the motors on a side is shorting, putting into a break mode, so it causes the other motors to work harder to overcome the motor that's not spinning.
Otherwise I would rewire everything and make sure there are no shorts.
I would advise not daisy chaining the electronics on the robot, I have all my teams use
Anderson Power Poles or
Wago Levernuts, so if there is a wiring issue, everything down line doesn't go down. Especially since the voltage sensitive Samantha module is always the end of the line in the daisy chain wiring scheme.
