Black Plastic Parts Coming Out of My Beko Washing Machine

I have been using my Beko washing machine for 6-7 years and have not had many problems, but for the last 2 weeks, black plastic-like pieces have been sticking to the laundry. I have washed the inside of my machine many times with detergent, but I have not found a solution. I have to constantly shake my laundry after washing, the pieces cover all the laundry, big and small. I do not understand what it is. I have used my previous machine for 20 years and have never encountered such a problem. Arçelik quality must not be like this.
