Help needed -- Eachine Wizard x220 MOTOR/ESC problem ?

[Nightcrawlerpt]

Anyone can help me?
I dont know what is happening with my drone, but sometimes, in mid-flight one of my motors kinda gets stuck and the drone flips over and fall (video below).
I didnt had any major crash, but i suspect it can be one of the ESCS.

Also i have recently flashed Betafligt on the wizard and i calibrated it, but didnt seem to make a difference.

Any ideas how to fix this?

Most probably a bad motor or ESC. Easy way to test is to swap 2 motors and see if the problem follows the motor or stays with the ESC.
