How to get fast sign in option functional again? Windows 11

Question

In the past I had no issues with the fast signin option, but lately, it completely dissapeared. I cannot see other users when I click on the user name in start menu, and I cannot see Switch User in CTRL ALT DELETE menu or everywhere else.

I tried fixing this issue in the gpedit.msc, I disabled the option to hide fast sign in option - didn't work.

I added a registry ([HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]

"HideFastUserSwitching"=-) - still no success.

A bug I found, they appear back when I modify either way "Always use classic logon", the option appears but for a very brief time, a few clicks and it is disabled again.......

It seems it hapens the same if I modify other settings in the same gpedit page.

Why does it switch of automatically???

PLEASE help me with this issue, is very frustrating!!!! Windows 11 is the worst, so buggy!!!
