How do I stop my Mac from trying to open new tabs when I make normal clicks?

Yesterday I was using musescore and was playing around with keyboard shortcuts and eventually my mac is now acting weird.

Every time I click on something it opens a new tab (on all my browsers) and I figured out it was NOT a browser issue because when I click on an app on my Dock instead it opens the finder at the application folder which is very bizarre. When I click on icons on top right it doesn't even opens them.

I tried restarting my computer in the hopes that whatever mode I got stuck on would refresh but no luck.

Does anyone have a suggestion on how to fix this?

Solution 1:

For now it seems what solved my problem is completely shutting down the mac. I am not sure why restarting didn't work but shutting down and then turning it back on solved it.
