Hi everyone!
I was tuning the desktop settings, first changing the background image and then adding some new widgets when noticed that exiting the widget screen ( that one that move all the icons in the desktop and leave it free) didn't go back to the original desktop, It took me back to an empty desktop (I had only 1 folder that couldn't see) and a panel that was still there. Weird...
Then trying to get the folder back I did logout, enter again and nothing happend, was the same
OK I realize some update notification and proceed to do it. Nothing change...

Well reboot may work, right?
NOPE

Now I have no desktop, no widgets, no menu and no "explorer" (dont know the linux version name for it) BUT my panel still there working properly.

I don't know what widget that is but from your description it sounds as though it worked as designed and did exactly what it was supposed to do, remove all desktop icons. Have you tried uninstalling the widget? You should be able to do that from your panel, which is still there.

I did not install any widget, I was just trying to add some widget to the desktop, and when close the widget panel everything went broke.

Other thing I realize is a huge RAM consumption (95% used) from plasmashell login with other account, and this user have the explorer but not the desktop.
Runing plasmashell ends in a infinity loop where grow the RAM consumption. Displaying this:

It is important to know what widget and what version it is. It could be the one crashing your desktop. Based on your screenshot, I think your panel also crashed. What's the only thing left is the conky that is running.

I have recently encountered a similar problem with an older version of Event Calendar widget that I had saved (.plasmoid file) long ago and which I then applied to whichever Plasma distros I have:

1. KDE Neon - through the provided upgrade paths, I upgraded my Neon install through 3 successive LTS releases already. Each time, I would reinstall that old plasmoid file for Event Calendar

2. Sabayon - rolling distro - installed Event Calendar just once, long ago

3. MX-KDE (this was a pretty recent install but Debian's Plasma version is 5.14, which is much older than the other 2).

Recently this old version of Event Calender widget caused the whole plasma desktop of KDE Neon and Sabayon to totally crash when you log in. Black screen, no wallpaper, no panel, no widgets. Only my conky was running.

Some web research revealed that the old version of said widget was no longer working with the latest Plasma version. The advice was to remove the old widget and download/install the newest version of Event Calendar from KDE Store.

But how to remove the old widget when your desktop has crashed and there is no GUI at all?
- If you are comfortable with command line and know where the plasmoids were saved, you could log in as tty (text console) and remove the file
- boot into live USB of MX Workbench, mount the said distro's partition and remove said file

File location: check $HOME/.local/share/plasma/ or its subfolders.

I did not set any widget, I was adding into the desktop a widget, see it, and the remove it.

Only have plasma_icons/ and plasma_notes/ in .local/share.

Plasmoids are in /usr/share/plasma/plasmoids. I remove the calendar folder and nothing happend after reboot

The Calendar widget in Plasma (usr/share/plasma) is NOT Event Calendar. You've just removed a default widget that comes with Plasma.

I was adding into the desktop a widget, see it, and the remove it.

WHICH widget?

You've added a Debian Sid repo to a Debian Buster-based distro rather than using MX Package Installer, Test Repo tab, to install the Proton VPN client that's been backported for MX. See Don't Break Debian in my signature. I think you need to reinstall MX-KDE.
