If this was a new motherboard, you need to activate it using your old windows 11 (or 10 or even 7)   key.

I assume you simply re-connected the existing SDD or HDD and booted up.

If it is a used motherboard then download ShowKeyPlus from the microsoft store and use that key to activate.

If you installed windows from scratch did you use the Pro or Home version?

You might put your old serial number into the following url and see if your old windows 11 was Home or Pro.

If you have a problem activating then call the Microsoft number shown on the activation screen and tell the representative you had to replace the motherboard.  If you  get denied try calling back a few hours later to get another rep.  Use a smartphone

Microsoft has help for activating after hardware change.
