Winclone9, Windows 10 clone/reboot blank screen with spinning cursor

Googled, appears this is a years old issue, still not resolved?

Mac OS 10.15.7, Latest Windows 10 home on internal hard drive. clone to another bootcamp partition with bigger size. SIP disabled

Confirmed the original still boot fine. The new one shows blank screen with spinning cursor. Tried Ctrl+Shift+Windows+B, Windows+P. didn’t work.

I would appreciate if any one could help. Why cloning an operating system has anything to do with display?
