Windows 2019 Standared VM can not be activated after lift-and-shift migration from on-prem Hyper-V host server

Question

We have lift-and-shift migrated 6 VMs from on-prem hosting Hyper-V server (Windows 2019 DataCenter edition) to Azure.

4 of them are Windows 2012R2 and 2 are Windows 2019 Standard.

We choose "pay-as-you-go" licensing for those migrated Azure VMs, as we don't have the software assurance agreement,

The 4 Windows 2012R2 had no issue being "activated" as soon as migrated to Azure, but the two Windows 2019 Standard can not be activated -

When I tried to activate in "Setting", I got below error:

Tried to request a "support" within my Azure Admin Portal, and got directed to this article which did not solve the issue,

Called MS' license hot line twice - got dropped while being transferred to "technical support"...

Any help would be greatly appreciated!
