Differential Unit Problems of BMW 325

Driving on 12/12/2019 on interstate highway about 65mph, going straight, when all of a sudden rear wheels (this is rwd - 2003 BMW 325i) locked up completely - the vehicle went forward at about 45 degrees sideways before it straightened out when the speed dropped. Thankfully I did not hit anybody, and no one hit me although there was quite a bit of traffic on this multi lane interstate. I got aaa tow it home. He had to drag it onto the truck bed as the rear wheels continued to be locked up. When I removed and opened the differential tapered roller bearing rollers were in the oil space. Looking to see where they jammed the system up I noticed marks on the carrier. It appears rollers jammed up in between the carrier and the inner wall of the differential box - see photographs. They may also have jammed up in between the gearing but I did not notice marks on the teeth but did not have time to spend to look more closely.
