You must be executed that /setconfig con_fontscale 999 command. No worries. Press Windows key, select Run, type in %appdata%, press enter. Go to the VCMP folder. Find some kind of text file named config or something. Open it and find a line saying con_fontscale 999 or something above 5 or 10. Edit it to con_fontscale 1 or 1.5.
