Uncollected Social Security and medicare Taxes (Employer is out of Buisness)

Hello All, 
I was a resident alien for the tax year 2023. While going through the 2023 W2 for the company I worked for, I realized that social security and medicare taxes were not collected. I am unable to reach out to the company now because it closed down and shut down the operations. What steps should I take to pay the unpaid social security and medicare taxes?
