'Root element is missing' when clicking 'Hosting' after an automatic Windows update

Last night my Windows 11 (Home edition) executed an automatic, mandatory Windows update to 261000.4652

When I opened up my Lighthouse project and clicked 'Hosting', a pop-up prevented me. It says 'Upload Data failed. Root element is missing'

The Chinese text is: 'Root element is missing.'

ALL PROJECTS IN MY COMPUTER ARE LIKE THIS. And I searched for it on Internet, I believe its an operating system-level problem. Now I have to upload my projects through another computer.

How to fix this?
