Have you tried to Restart your computer?  That is always a good first thing to try if the software was previously working.

The next thing to try is to type in %appdata% into a Windows Explorer app. You will see an Ansys folder. Rename that to Ansys-old in the Roaming folder. Now go up a level and down into the Local folder. You will see an Ansys folder. Rename that also.  Now start Ansys and see if that helped.
