Just to confirm, have you tried using a different browser? If the issue only occurs with the browser that you are using, we suggest that you uninstall and reinstall it to your PC. We also encourage that you regularly update your device to make sure that your computer is on its maximum performance.
To check for the latest update, go to Windows Update by clicking Start > Settings > Update & security and click Check for updates. It will scan and install all the latest updates available for your device.
Let us know if the suggestion works for you.
