@Kylen: As the Google Photos app is already housed in the Google folder in your apps menu, then this might be why you're experiencing difficulties moving it. It looks as though @BandOfBrothers may have customised the existing Google folder by adding and removing some apps, but leaving Google Photos where is is? Sadly I'm unable to troubleshoot this as I don't have access to an S10, or Android 10 device, but can you try going to Apps > Google (folder) > Press and hold on Google Photos, and drag it out of the folder. Are you able to do this? If so, press and hold on Google Photos once more, and drag it over another app, and this will group them in a folder together.
@Kylen: That's strange, because these apps should have been grouped together by default in a Google folder (default folders are Google, Samsung and Microsoft). Have you tried pressing the '+' (add) button in the Google folder, as well as dragging and dropping Google Photos? What happens when you try and add it?
@Kylen: What happens if you open your created Google folder, tap the '+' button and select Google Photos? Silly question, but covering all bases, have you tried adding another app to the Google folder, just to make sure it's not at capacity (if that's even possible)? Failing that, it may be worth creating a new folder with Google Photos in it, and moving all your Google apps there to see if you can work around it that way.
