Can you please give me/us some more information?
also can you explain what you mean by 'Druging'?
Invalid font may be because you do not have the font installed or it is corrupt.
Can you list all of your error messages in bullet points and a little description under the error code/name?

Have you tried to reinstall your fonts?
Also, open up a brand new project file and see if it has the same outcome when you start up or either make new text with those fonts.

Control panel > appearance and personalisation > fonts > right click and uninstall.
Do that for the fonts that are not working, then find them on the internet and reinstall.
