According to service agent my cars oil housing or something likely was stuck in engine and caused it to lock up not even 1/4 Mile from shop? The black circular piece?

Ouch, sorry to read about your loss.
The black circus is an "O-ring" seal. It's included with every new MB oil filter.

Quite common that people doing the service without checking the manual put the oring in wrong grove, what leads to oil loss.
Too often today's oil changers are yesterday's burger flippers.

Sounds like they forgot to put oil back in your engine.
The seals are in place to separate oil flows going in and out of filter. Missing or wrongly placed seal does not prevent oil flow thru the filter housing. It just would not filter all of the oil as not all of it flows thru the filter media. Oil would still lubricate the engine though.

How does a wrongly placed seal (other than the housing seal) lead to oil loss?
Blue arrow shows proper groove, when uneducated servicemen are tempted to put oring in red groove.
Red groove will hold some pressure due to tension, but at higher temperature/pressure it will blow.
What Arrie said. Did they remember to put oil in your engine?
A misplaced cap seal wouldn't dump enough oil to seize an engine after two minutes.
Missing oil surely would.

Absolutely,
If the filter housing O-ring seal was even left out it would not let oil leak out in just 1/4 mile drive in amounts that the engine burns up, no way. And there would be very visible signs of the oil leak.
This car was driven without engine oil or coincidentally the oil pump failed during the oil change....your pick...
Did they not check for oil pressure after change and do the start up where they check for leaks?
I mean after an oil change one of the things you do is crank engine and ensure you get oil pressure build up -
Yeah these cars do not have oil pressure gages but I would hope they use thei fancy tools for the price they charge.
but while waiting for oil pressure to build or after someone or same tech looks under engine for oil pouring out and then examines engine from underside and top to ensure no leaks.
Did you check oil level after it siezed? (before it got back to dealership?)
Most dealerships have a system and procedures etc to ensure this kinda crap does not happen since a $20k engine costs way more then their $200 oil change.
I mean oil changes are cheap - but if done wrong can be dayum expensive.... more so then any other maintenance.
Do not change plug - it runs bad is all.
Do not change filter - it runs bad
etc.
Bit forget oil or oil changes and woof you next visit is to the Walletectomy doctor.

Modern MB engines don't have oil pressure sensors, when level sensor acts with delay.
That is why I think that oring installed in wrong grove could hold for some time, till at highway speed the pressure blow it and it doesn't take that long to blow 7l of oil.
By the time the light come on, driver notice it and reacte, the engine very easy will be toast.
With OP not coming back with more info, we can guess endlessly.
E350 is quick, but not that quick in the quarter mile...
and that assumes he left the garage and floored it.
Which of course has its own implications on a stone cold engine.
Nice post-n-run by the OP.
Modern MB engines don't have oil pressure sensors, ....
Wait, so no PRESSURE SENSOR at all for computer to read and give LOW PRESSURE WARNING IDIOT LIGHT?
OMG why to save $5?
I know they do not have pressure gages but ya think they would still have sensor so it could tell driver to shut her down with low pressure by flashing IDIOT LIGHT or IDIOT LED Screen.

The pressure sensors become controversial in synthetic oil era.
Those oils can provide good lubrication without heavy weight old oils require, but when you put thinner oil into old engine, the pressure will be much lower.
I used to drive 1998 SL500 in Las Vegas triple-digits temperature and oil pressure gauge would stay on 0 when idling.
That was raising red flag with lot of owners and I think this is one of the reasons the gauges were replaced with idiot lights and then pressure monitoring got deleted all together.
Why spend money on something that is not needed and brings troubles from customers?
So the oil level sensor is the only thing that will warn you about oil problem. I noticed it comes with few seconds delay, at least on yellow warning.
Yellow warning come when oil comes to min on dipstick and usually warning is "Add oil at next fueling".
Than when level comes down too far, you will get red warning and I think those cars have software, who will shut the engine off at some point, but I never went that far.
Well, if the oil filter is still dry...
I get the sense that if a shop forgets to fill an engine with oil until after it is seized, they'll also forget to dip the oil filter in oil to cover their tracks.
At any rate, oil starvation is pretty visible on bearings and cams and about everything else that needs oil to move properly.

I am still awaiting the shop to try to determine what went wrong and I gave them permission to tear into engine and hurry up and wait kind deal. I work lots of hours and don’t a lot of free time to be on internet.

Hate to say it but if this is the same shop that did the oil change I fear you are gonna get screwed. More than likely they will create some situation that would cause it that is the engines fault. GL though, hopefully it works out.
