Rename not working in File Explorer on Windows 11

For an unknown reason, File Explorer stopped letting me rename folders. It lets me create them, it lets me rename files, and I can rename files & folders using the Command Line. It is only File Explorer renaming folders that is a problem. I have done a Windows Repair (and several other things with the help of Copilot), and I am using Windows 11 Home 25H2 26200.9168 on a Surface Pro 11. Has anybody else had this problem? Any help would be appreciated.
