Hi! Let's see if we can help you!
What version of the Operating System are you using? Catalina? Big Sur? Safari is your browser...and doesn't really have anything to do with Photoshop.
And what build of Photoshop is your 2021 version? 22.3?
Have you checked to see if your system meets the requirements for running this version of Photoshop? Here is a help doc to check: https://helpx.adobe.com/photoshop/system-requirements.html
Please give us a little more information so we can help!
