Numerous sources already, check out VASaviation or Mentour Pilot on youtube, it looks like they flew through a rapidly growing thunderstorm and encountered extreme icing conditions. That will rapidly destroy the aerodynamics of an aircraft, and their subsequent stall and overspeed condition is a completely plausible outcome of such a situation.

This is clearly not what happened and it would be stupid to believe this happened with this flight because we already have public information that’s why. No way that gets swept under the rug the day before midterms.
