It's the exact symptom of faulty intake cam position sensor. Both of our M54 did exactly this at about 130,000 miles and 14 years.

The main times they would stall: pulling into 90° parking spaces or pulling forward from a stop in a left turn lane when a light turns green but waiting for oncoming traffic.

On my first one I spent over an hour fishing three wire under the intake on the second I just routed the wire over the intake in 5 seconds flat.

Do not use knock off sensors! Get an OEM sensor or you'll be plagued with mystery problems! CPS very rarely ever causes code related to cps.

Only one of our m54 had an exhaust CPS fail and that was years after the intake so I would suspect intake first.

My e53 had ses/mil lit when I test drove at auction. Self cleared by delivery & when it came back the randomly unrelated code led me to xoutpost and miraculously somebody had the same random unrelated code but identical symptoms. New intake CPS OEM bought from Amazon for about $90 was my first BMW repair.
