Ive replaced probably a hundred oil filter housing gaskets with no engine failure, this whole thing sounds like b.s. I’ve also repaired several shredded belts as a result of leaking oil filter housing gaskets.
Nine out of ten times when the belt shreads it gets sucked into the engine and gets tangled in the timing chain, it also sometimes gets sucked into the oil pickup. Any time the belt shreds like that the crank pulley should be removed, and the front seal inspected. If the belt was sucked in then the oil pan and valve cover NEED to come off and all traces of belt removed.
None of what you say they did makes any sense. Any half competent BMW tech knows about this relatively common issue and should know what to do if the belt shreds. Also I do not understand why they would replace an oil pan gasket and not the leaking oil filter housing first, as the oil filter housing is a much more obvious and critical leak. Not to mention when it leaks badly enough oil makes its way around the seam of the oil pan and makes it look like it’s leaking when in fact it may not be.
As a tech myself usually when these types of threads pop up I can see why a shop did what they did/charge what they do, but if the chain of events are as you said, in my opinion your engine failure is their fault. Also if they are under the impression that the crank and or rod bearings cannot be starved of oil because they “bathe in oil” I would not trust them to change a light bulb much less rebuild an engine. Unfortunately this is a prime example of why to go to a dealership or well known independent Bmw specialist.
I’m sorry if this isn’t what you wanted to hear, I do hope everything works out for you. Good luck
