External Hard Drive disappeared on Finder, still shows on Desktop and opens to Finder

I have two external drives connected to my iMac. Recently, only one appears in Finder.

I have a Mac Mini M2 Pro, so there is no PRAM, etc to reset.

The drive appears on my desktop, and I can click on it and a Finder window appears. I can navigate the drive normally, open files, etc.

The drive also is recognized in Disk Utility.

I have tried pulling com.apple.finder.plist out of Library, and this has not worked.

My problem is that apparently, a lot of apps I use (e.g., Lightroom, Photoshop) use Finder or an API to show files, so I can't get access to the almost 2TB of files on that drive in these applications.

Thanks for any help!
