Over the past few months, I've been stuck trying to get the on-board VIO system to be stable enough to follow a path to completion, however, the sudden switch from manual/positional to offboard mode leads to voxl-vision failure as it tries to move suddenly to a waypoint or to its origin. I've also encountered voxl-vision failures using the positional hold mode. It only works sometimes when at 90-100% battery charge, These failures have lead to several crashes/replacement parts being required

Please let me know if there is anything specific that might be causing this and what I am missing, I am using a properly lit environment with a colored carpet/floor, it is an indoor GPS-Denied environment and I have tried the documentation methods for solving this issue, it is also using factory-defaults.
