Drone motors stopped mid-hover, possible PX4 MAVLink issue

I had a crash with my drone and I’m not exactly sure what caused the failure or how I can prevent it in the future.

My Drone is a VTOL with PX4 17.0 with a Cubepilot Cubeorangeplus

I was trying to tune my drone, so I performed several hover tests. During the last one, after a short time (about 20 seconds), all motors suddenly shut off and the drone fell. Before that, all tests had gone well, and my first checks did not indicate any hardware issus, like power or voltage issue.

In the fault file, I found an error related to mavlink_if1. My MAVLink instances are actually supposed to be disabled, so I’m a bit unsure where the problem came from or whether the flight controller itself may be damaged.

Here are the logs:
