If it is macOS, I can think of a similar workaround for this issue that was addressed yesterday by ACP Karl Heinz Kremer to a MS Windows 10 user.
It seems like the file viewer (in macOS the "Finder" file viewer) hogs certain applications as if they're used by another program when you have the "Preview Pane" enabled.
In MS Windows 10, openWindows Explorer, click on the "View" tab and clcik once on "Preview Pane" to disable.
In macOS , open the Finder, click on the "View" in the menu bar and select "Hide Preview Pane" (or "command"+"shift"+ "P" keyboard combination).
