Using any of the Advanced or Develop menus is risky, so you should leave them alone unless you know what you are doing.  Fortunately, though, the solution to a problem like yours is fairly simple.  You will need to delete all traces of the viewer from your computer -- including all hidden files, where those settings are stored -- and install a new copy.  The process is known as a Clean Install, described here >>> https://community.secondlife.com/t5/English-Knowledge-Base/How-to-uninstall-and-reinstall-Second-Life/ta-p/1375231

Sounds like you changed the User Interface scaling size in the preferences panel, if you cant manage to find and alter that, you might have to do a full clean install, which would mena uninstalling the viewer, then going to the C:\Users\[your windows login name] subfolders where your viewer stores your personal settings and deleting those too, then reinstalling the viewer.
