Hi, good day!
How did you originally obtain your Windows 10 license? Did it came preinstalled with the device? If so, it is considered an OEM license and cannot be transferred from motherboard to motherboard.
Please try to launch and run command prompt as administrator.
Execute the following command
slmgr /dlv
Please take a screenshot of the resulting window and post it in your next response. Thank you.
I look forward to receiving your update and I'm willing to collaborate with you till we resolve the issue. Do keep me informed.
