I use Google Drive File Stream on Windows. I used to be able to open a Google spreadsheet from an explorer window just by double-clicking on it like any other file. Now I can only open them by right-clicking on the document and choosing "Open with Google Drive File Stream".
If I right-click and choose "Open with..." I get this; I've already checked "Always use this app to open .gsheet files."
The entry in "Choose default apps by file type" is correct:
Is this something specific to my setup, or is this a change that affects all users?
