there is a way to get the old windows 10 taskbar back in windows 11. It does require some tweaking of the windows registry so you do so at your own risk, make sure you set a restore point and back up settings before you do any of this. The bonus of following this guide is that not only do you get the windows 10 taskbar back, you also get the old right click context menus back, Windowblinds will work again (well mostly, i haven't come across any areas where it isn't at the moment). And there is no guarantee that everything won't just revert back again after the next update, Windows 11 is a work in progress as we all know, so you need to decide just how much you want the task bar back.
and please follow the guide carefully and the steps in the same order the article recommends.
again i stress all this is at your own risk.
