Lift motor seemed to stop and restart on mode switch (Custom 4+1 Vtol)

Good Day,

I am a little bit confused as to what happened in a flight the other day. Did a transition and transitioned backed to QHover, then started to descend in QLoiter. Fairly low to the ground, the plane seemed to lose the right front lift motor. In an attempt to recover, I switched to QLand and the plane seemed to recover for a brief moment before becoming unstable again and hitting the floor quite hard (Will be quite a rebuild… Hahaha)

Attached is a link to the logs. If someone could have a look at them and indicate if they see something out of the norm, i would appreciate it.

Also attached is a log from earlier the same day where there was no apparent issues.

Thank you in advance,
