Task Center cannot be entered/loaded

Unable to enter the task center even after switching to different devices

More information is needed. By “task center” are you referring to the “Mission Hub”? When you say “different devices” what do you mean? That kind of implies phones or tablets. The Mission Hub is designed to run in a browser on a desktop/laptop system. I don’t recognize the browser you are using. Without any of this information it is difficult to diagnose the problem.
