Windows 11 clicking taskbar icons doesn't bring the program window to the front

I have an issue with Windows 11 and its already opened taskbar programs. By clicking the icon the program's window is not brought to the front if the particular program has multiple instances/windows open. If it has only 1, then it works. If multiple, nothing basically happens and I have to Alt + Tab to bring it to the front.

I have

1. Upgraded Windows 11 from Windows 10 (not a fresh install)
2. Installed Explorer patcher
3. Uninstalled Explorer patcher when it stopped working after a system update
4. Noticed this issue.

How to make the taskbar work so that by clicking the icon on the taskbar the particular program would be brought to the front even if it has multiple instances open?

Pic 1. If a program e.g. File explorer has more than 1 instance already open, clicking it on the taskbar does nothing

Answering to my own question. It turned out that having the taskbar on the top was causing the issue. Had to bring it back to the default position on the bottom and the problem was fixed. Now hovering on the programs in the taskbar would show the popup.

You can bring the taskbar back to the bottom by changing the value from 01 to 03 in the registry in Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\StuckRects3 as in the image below.

It would be nice to have the taskbar at the top, but apparently, it is not properly supported in Win 11.
