Option + Command + Spacebar opens Searching this mac window instead of Finder

A normal Finder window used to open when I pressed Option + Command + Spacebar but not its a Search window. I know this happened once and I found how to fix it but I can't find it anymore.

I found a solution to the issue. OptCmdSpace has always been a command for showing a "finder search window". If you now just see a window without the sidebar just do this:

• press OptCmdSpace To open this window
• Press OptCmdT or go to "view>hide toolbar".

Sometimes we just press it accidentally and this hides the toolbar, which makes this searching window into a "normal finder window".

look in system preferences > keyboard > shortcuts pick spotlight. see Show Finder search window. maybe it got unchecked?
