I didn’t know for a 100% sure, but looking at your video (seeing the motion to the left rear corner) and into the gcode file in Bambu Studio, where you can enable the “travel” moves, but there was no travel move in that direction on any layer.
That made me think about another recent topic: Vision encoder issue - Bambu Lab H2 Series / Bambu Lab H2S - Bambu Lab Community Forum where also a layer shift was triggered by a motion that possibly moved out of the given range of the printer.
Adding those things together was eventually the trigger.
First of all I am glad you are getting a good part now!
Secondly, this would definitely be a case to report to Bambu Labs, so they can take action on this.
@SupportAssistant please review this discussion on sudden layer shifts triggered by a Timelapse move.
And possibly review the topics regarding the Vision encoder triggering a similar layer shift behavior.
