That's been my assumption as well - the movement of SLF upset the aircraft CG sufficiently that the pilot(s) lost control and stalled.
A skydiving aircraft crashed around here about 30 years ago when the pilot lost control and stalled due to the rapidly changing weight and CG while the skydivers were doing their thing. It's been long enough that I don't recall details, but there were several fatalities.
