Hi Sumi1962,
I am Dave, I will help you with this.
Rest assured that does not indicate a problem, that Performance Logs folder will always have that exact date after a full clean install it is the date on that folder in the Windows 11 image, that happens to many folders and files after a full clean installation and will not affect your new installation, Microsoft have never provided an explanation why some files and folders on a new installation will contain the dates the original mage was created.
