Slightly different issue. The loading phase in MSFS 2024 is a bit different (and wilder from a physics standpoint) according to Nick, so the chocks are being added and then removed because the plane is moving while loading in.
What I suspect is happening to OP here is similar; it has been seen here before that sufficiently high winds will trigger Nick's code to remove the external power and chocks because the plane is in "motion," but it's just because the weather is bad.
