Windows 10: How can I reactivate my Windows 11 Pro FPP license after changing my motherboard and seeing...

Description:I am having trouble reactivating my Windows 10 Pro Windows 11 FPP/Retail license after changing my motherboard. I purchased the license from Shopee and originally activated it on my dad’s PC. After replacing only the motherboard and reinstalling Windows 10, I tried to activate Windows with the same product key, but received an error.Error message:"Unable to activate Windows. We can't activate Windows on this device because the product key was already used on another device. If you think it wasn't used on another device, select Troubleshoot below. 0xc004c008"System Information:O

Motherboard change unable to reactivate Windows 10 Pro -

I have searched this topic and everything seems to be almost a year old. This is a homebuilt machine circa 2015. It started with an ASUS FM2+ motherboard with an AMD A5600K processor. It was Windows 7 Pro, upgraded to Windows 8.1 Pro then to Windows 10 Pro.
Saturday the motherboard died. An exact replacement could not be located so a Gigabyte card was installed. No changes to the hard drives. Booted the machine and Windows automatically started and then did a "revert" then installed the latest updates. C Drive was in the red so I deleted all of the old install files using Windows Clean-up. Went to reactivate, checked the significant hardware change and entered my MS account information - The computer (none of my computers) were listed and now it is telling me that I have to spend $200 to buy a copy of Windows 10 Pro.
Have not yet called Customer Support as the computer is at home and I work during the day -
I do have a disk image or two that may be a year old -

Suggestions - should I just shell out the $200 and move on

TIA
