It seems that you might be experiencing performance issues after a recent update to Windows 11. There have been reports of problems with applications and pages running slowly or not opening at all following certain updates. To address these issues, it is recommended to check for any additional updates that may have been released to resolve these performance problems. You can do this by going to the Windows Update section in the Settings app and selecting "Check for updates". This will ensure that your system is up-to-date with the latest fixes and improvements.
