Hi Hande,
Welcome to Microsoft Q&A forum. I'm happy to help.
After doing some research, I've found this GitHub article: "WSL2 is not supported with your current machine configuration" after enabling Hyper-V, Virtual Machine Platform, Windows Subsystem for Linux, Hypervisor Platform and virtualization in up-to-date bios. #9652.
Please try following suggestions on the article to see if they help.
If you have any difficulties along the way, please feel free to let me know.
