Oil quart foil seal accidentally poured in during routine change

[dummkopf]

Username says it all.

Please don’t ask how this happened as I am still beside myself that it actually did!

I’ve searched the web and although this happens more than I thought, I couldn’t find anything specific to a Boxster motor.
I’ve filled and drained the oil twice hoping it would wash the piece down into the sump but no luck.
I think the piece is large enough to totally occlude the oil pickup tube so don’t want to start the car.
I’m guessing it may be stuck somewhere in the crankshaft bearing carrier.

Does anybody have constructive suggestions on how to proceed?

I've attached a photo showing the size of the piece of foil.

Car is a 97 Boxster.
Thanks in advance.
