Lost Karta Pobytu while outside of Poland for a US citizen

Hello,
I am a US Passport Holder and I am currently residing in Warsaw, Poland. Unfortunately, while in UK for work, my wallet which contained my Karta Pobytu got stolen. Can I still return to Poland or will I get hassled a lot?

What are my options? I do have a picture of my Karta Pobytu - front and back.
Thank you for any guidance/tips.
