Can't open the taskbar pop ups for network, audio and calendar/time&date

I have Windows 11 Pro 22H2 22621.1848

This morning I start my PC and when I wanted to check the calendar for some information, I click it in the lower left corner and nothing happens. I click it a few more time, nothing happens, then I try to click all the other icons - volume, network, language input methods selector.

Out of all of them, only the language output works, the rest do nothing. I accidentally found out I can still adjust volume levels by scrolling up and down while hovering over the volume icon, but this isn't a solution.

I'm asking for help how can I fix this, because I dread the idea of having to reinstall ... AGAIN. The reinstall isn't the bad part, but having to reinstall all my programs after that is what scares me.

Here I've posted a video with the problem:

In this video, i will show you how to do a repair install of Windows 10 by performing an in-place upgrade without losing anything.

Here is the text versions of the Repair install...




Here is the short version of the In-place upgrade tutorial...

DISABLE non-Microsoft:
a) antivirus software
b) firewall software
c) drive encryption software

Make a full OS backup with a program like Macrium Reflect or AOMEI Backupper Standard
Making a backup is optional, but always a smart move.
If you had a backup from before this problem occurred, you wouldn't be reading this.
Macrium Reflect
AOMEI Backupper Standard (free)

Click to expand...

Get the Windows 11 ISO image and save it to your desktop...

Right click the ISO image and choose: MOUNT
Open File Explorer and you will see a new drive letter. It will "look" like a DVD optical drive.
Double click the new drive letter to open it.
Find setup.exe and double click it to start the in-place upgrade.

Choose the Keep personal files and apps option.

After it's all done... to UNmount the ISO image, right click the new drive letter and choose: EJECT.

The ONLY thing you will lose is some of your personalizations.
Your drivers, programs and data will be intact.
