The ⌘+Tab key combination switches between active and background windows on my MacOS on MBP.

When hitting this combination, a small preview of the selected window appears. Another hit on the Tab key while is pressed previews and selects the next window. Releasing the switches to the currently selected window.

Recently, this preview does not appear, so I can't efficiently switch to other windows using a key combination.

Any idea how to restore that preview, please?

Solved by rebooting. The preview appears correctly now.

Try going to System Preferences > Keyboard > Shortcuts > Restore Defaults

Have you tried restarting your machine and doing your system updates? Have you tried using the right and left command key with tab to try and make it work?
