What bl controller does it have, AM, Martinez?

First thing, check cables to the motors. Most problems originate from the cable routing to the motor. Just the weight of the cable, cable swinging in prop wash, will affect it.

Next thing would be to redo calibration of the controller.

That don't do it then it's time to look at the controller firmware for updates. After that, it's all in the PID settings.

It looked good until it happened with no twitching.
Other things to look into, does it have ferrite magnets on the motor leads? THese should be as close to the connector as possible and no weight suspended on the unsupported cabling to the motor itself.

These things are prone to voltage issues. They don't like noise at all. A good lc filter on the power lead powering the controller is cheap insurance, even if you run an independent battery.

Now you know why you don't want to run the GoPro on a gimbal as your only fpv camera!
