      Every time I try to create a new world or launch an existing single player world, right after the message "Saving world..." Minecraft keeps crashing with the error 
      java.lang.NoClassDefFoundError when trying to initialize the class sun.net.www.protocol.https.DelegateHttpsURLConnection. I am using macOS Catalina (on a 2019 MacBook Pro) and version 1.14.4 of Minecraft (I had the same problem trying 1.14.2 and 1.13.2).
