After an attempt to format a fake USB key (I know it's not done...) I noticed that Macintosh HD is not displayed in utility disk in normal boot. A snapshot is clearly visible in its place. Instead in Recovery Mode everything seems to be fine.
Does anyone have any suggestions for fixing this?

The crypto-locked System Volume is mounted as a Snapshot in normal mode. This is another way to insure it can not be modified by any ordinary means.
If that snapshot does change for ANY reason, including corruption, the crypto signature will change and you will be notified to re-install MacOS from fundamental sources.
it's not broke.
In Normal mode, the Macintosh HD container holds the ACTIVE System (a crypto-locked snapshot) and the data Volume.
In Recovery mode, you are running from the MacOS Base system shown lower in the pane. It was a Disk Image, expanded from the Boot ROM, and it does not use a data volume, it creates about 30 RAM-disks to hold temporary items, which do not appear in Disk Utility (but do appear in Terminal DiskUtil list.)
The Macintosh HD container does not include an ACTIVE System Macintosh HD Snapshot, because that is Not ACTIVE and not Mounted in Recovery.
In Recovery, the boot drive is completely available for Deep repair.
Thanks for the info, so now do I have to do something or can I stay in this configuration to have my Mac in normal condition?

its not broke, there is nothing to fix.
Do you notice any additional GROSS symptoms that led you here? If so please elaborate.
Nothing else, everything works fine.
Thanks for support.
