Just installed on Windows 10 Version 1909 OS 18363.836.  Hangs whenever I try to do Step 1 of the docs, set decryption.  Debugged in VS 2019, access violation trying to read 0x00000, NullException.  Finally, shutdown all of my work and restarted machine.  Error cleared and this time asked me to accept the new Cert.  

What a terrible first time experience.  Issue resolved.
