Shared Drive not Showing up in Google Drive

[Horsman]

I'm losing my mind on this, and it's probably something simple, but here I am.

For some reason a Shared Drive is no longer showing up in my Google Drive desktop app. I am the manager of the drive and it previously showed up through the desktop app. The drive labeled 123w Shared Drive shows up in the website:

Anyone able to help me out with this?

On a related note, I was looking to try and change back to the 'alternate streaming method' as listed in the help here, however their solution "Check the box next to “Use alternative file streaming method to resolve potential application compatibility issues.” doesn't even show up as an option for me in any Settings I can find.

Thanks.
