I-485 and EAD: case is stuck with USCIS

[ABC_XYZ]

My priority date for I-485 (EB2 category) is 03 Aug 2009. My priority date became current in Sept 2020; however, USCIS has not taken any decision on my case yet. I even have not received RFE for my I-693. I contacted USCIS multiple times myself and through local senators/congressman also. But still no progress on my case. My EAD also expired in Aug 2021. I filed for EAD renewal in Mar2021. But no action on my EAD either. I submitted request to expedite my EAD and provided supporting documents showing need of continuous medical insurance my son due to his medical condition, and thus, need of keeping my job (my insurance is thr' my employer). But USCIS rejected it. If I don't get EAD/GC by 02/2022, I will lose my job and, thus medical insurance. What are my options?
Look forward to you suggestions. Thank you.

2 yrs back I was in same situation but mine was l2 EAD. I expedited again. Contact Ombudsman or congressman. Sometime it helps. Unfortunately this time around I am waiting for GC EAD and nothing is working. It’s been 75+ days after expedite request. It’s not rejected nor approved ????♀️
