While using Opera GX, I had a lot of tabs open so that I could do my work later. But one day, I accidentally opened a new window and closed the window where my tabs were open. Now, every time I open Opera GX, this window and the tabs open along with the window, but no matter how hard I try, I cannot access this window and the tabs in it. It's really tiring my computer, can you help me find a solution? If it continues like this, I will have to delete Opera GX and switch to another browser...
