Error when trying to start wireshark

I just installed Wireshark this morning (11/3/2019) on 64-bit Windows 10 computer. I got the error message shown in the image below when I clicked on Start. What does this mean? How do I correct it?

Unable to upload image (something about need >60 points). Here is what the error message said: The capture session could not be initiated on interface '\Device\NPF_Loopback' (Error opening adapter: A device which does not exist was specified. (433)).

Please check to make sure you have sufficient permissions, and that you have the proper interface or pipe specified.
