The Opera is opening two windows when I only clicked to open just one. I have already tested by right-clicking and opening the menu to select the option to open a new window, and seconds after opening it, a new window opens.

@albano23 Yay I followed your recommendation and got back to normal. Now it only opens one window, as it should! The good thing is that I didn't have to reinstall anything. I had to reconfigure Opera, just the preferences, extensions, those things. Thanks for your support.
