    SEVERE: NULL Preferences during startup

      Hi, I know you've answered this before but I can't locate where I found it and what to do about it if that recommendation doesn't work.  From memory, the recommendation was simply to navigate to users/me/appdata/sqldeveloper/roaming/sqldeveloper and rename the folder for the version I'm using which is 18.4.0.  I did so, restarted SQLDeveloper, and consistently get the same message and a new 18.4.0.  Also, after using it all day, it does start to get squirrelly and eventually locks up.  I kill it in Task Manager (Windows 10) and start over.  Thanks.
