Menu icon is gone

HI, a couple of days ago I had a problem with a dimm of my RAM memory and the computer didn’t start.
After solving the problem and replacing the faulty Dimm, the computer finally started, the problem now is that the icon (top right) that opens the menu is gone.I have re-started the computer several times but everything stays the same, icon gone.
The rest seems to be working normal, but I have no idea how to solve the problem with the menu.

press CTRL+ALT+T to open a terminal

type:

budgie-desktop-settings

Then readd the Budgie Menu applet to your panel.

Alternatively just reset your panel to go back to the default look and feel

nohup budgie-panel --reset --replace &

THank you!!, It is back!!
