Windows 10: How to revert back to Windows 11 Home Single Language from Windows 11 Pro for Workstation?

I unknowingly entered a product key of Windows 11 Pro for Workstation which I have forgotten now, after which it is showing that windows is not activated. On troubleshooting, it show that I have digital licences of Windows 11 Home Single Language on my laptop, and I need to install Windows 11 Home Single Language to activate that digital licence. What can I do now?

After troubleshooting I got the following message :

"We found a Windows 11 Home Single Language digital license for this device running Windows 11 Pro for Workstation. To activate using this digital license, ou need to install Windows 11 Home Single Language".

Please Help me Resolve this issue

 

Illegal product key for windows 11 pro workstation was used by my brother. But I want to go back to my Original Windows 11 Home single language. What should I do?

My laptop originally had Windows 11 Home single language in it (licenced).

My brother got an activation key from a lame "website". It worked. Now Windows 11 Pro for Workstation is in my laptop. It isn't activated properly or something like that (because it wasn't licenced).

How do I revert to my Original Windows 11 Home single language? Please help, because I just bought this new laptop.
