Is it possible to challenge cassation court rulings?

I gave a person 250,000 AED as a cash loan. I got a signed IOU letter with two witnesses.

Later on, the borrower gave me cheques for 100,000 AED and gave me a letter stating that this was partial payment of a bigger loan.

When the cheques bounced, I started a commercial case for 100,000 AED on the basis of the cheques, won it, and started an execution case.

Then I made a new commercial case for the remainder of 150,000 AED on the basis of the 250,000 AED IOU. I won the first instance and the appeal level.

I lost at the honorable cassation court.

The cassation court ruled that this new case for 150,000 AED was a repeat of the old 100,000 AED case and should not be judged again. It was RES JUDICATA.

What options are left for me?

Do I lose my right for the remainder of 150,000 or only lose the right to pursue it legally?

What steps should I take to recover my remainder of 150,000 AED?

Thank you!
