After Windows update, the user profile was lost.

Hello everybody,
The other day (March 8) my laptop updated from a previous version of Windows 10 to 21H2 (OSBuild 19044.1526)
This update changed my desktop with the usual files and shortcuts etc. missing.
I went to “RECOVERY” to revert to the previous version but it says “This option is no longer available because your PC was updated more than 10 days ago”. As of this writing, there are ONLY 4 days.
I also restarted several times but to no avail.
In the C:Users FOLDER there are 12 items (ALL of which are FOLDERS)

NB These are all FOLDERS
I would like to know how to recover my profile.
Any help would be grateful.
It is better to be silent and look like a fool than to speak and dispel any doubt.
Never argue with stupid people, they will bring you down to their level and beat you with experience.
If at first you succeed, try not to look surprised.
