What is your CPU ultiisation withn betaflight? And it might be related to this issue with DMA mode on SDcard logging -

Omnibus Quad Randomly starts twitching (when logging to SD card)

We have been seeing some reports of omnibus users reporting that their quad suddenly starts twitching at a random point in the flight. This actualy is caused when you enable blackbox logging to the SD card and is a bug on betaflight at the moment and seems to affect anything from V3.1. An example of this is shown in this video (the user is manually disarming the FC mid flight which causes the quad to come tumbling back down to the ground) https://www.youtube.com/watch?v=O9Sj2t8hNNU Fortunate…

But I am not sure if that is the same issue but might be worth disabling blackbox logging temporarily to see if anything changes
