All windows not visible. Only visible in task bar

as you can see there are no windows on my desktop and I cannot access them through alt and shift. I can see that the applications are running on the sidebar but even clicking on them doesn’t not do anything.

How do I fix that?

do you have maybe a second monitor plugged even if it is not switched on?

No,not at all

or maybe right click on the task manager - configure task manager - behaviour - show windows on all activities as opposed to just current activity

I cant open any windows,they are not visibale.
