Yes, but please do not install using the installation file over an existing installation.

Considering the inherent problems with the updater, I completely uninstalled StreamFab, this time I also specified to remove the configuration and also deauthorized it. Then I installed it brand-spanking new and authorized it again and NOW it properly detected and downloaded the available Disney+ 1080p video that it had been failing on before. The updater probably corrupted something (likely including my configuration). My previous uninstalling/reinstalling w/o removing the configuration did nothing to resolve. I had to opt to wipe the slate completely clean before it now works with the 6192 build.
Thanks for the guidance. NEVER AGAIN will I trust their updater!
