    Because those are probably not using D-Bus for anything. This is also showing 
    "plugins/bearer/../.." which is really weird. I've never seen this show up. I 
    don't know if we can attribute this to the NetworkManager bearer plugin (which 
    does use D-Bus) or if this is just a red herring.

    But there's a simple way to test: can you delete the NM plugin and see if the 
    problem goes away?

Thank you for the suggestion. I did the following (Hoping I interpreted your instructions correctly)

$ cd /opt/DREAM3D_SDK/Qt5.12.8/5.12.8/gcc_64/plugins/bearer
$ mv libqnmbearer.so bak_libqnmbearer.so.bak

Kicked off a new build. Results will be at <https://dev.azure.com/BlueQuartzSoftware/DREAM3D/_build/results?buildId=279&view=logs&j=1ee29c43-a44e-5e49-79a9-6f3da8136d88>.
