What can cause high insulin with low blood sugar? Besides insulinomas? 54-69 blood sugar 11-22 insulin when low.

Not much. Really besides insulinomas(which are exceptionally rare, so rare that even the largest of academic instutions have seen a large number of these cases) and people accidentally or purposefully administering too much insulin. But to be able to better interpret the data you provided, more information around the circumstances when these numbers were acquired is necessary.
