Hello, I deleted Opera and reinstalled it. After installing it, when I opened Opera, my search engine was Yandex. I changed it in the settings. When I opened a new tab, the search engine was still stuck on Yandex. When I looked at the settings again, it showed Google as the search engine. When I tried to delete Yandex, I logged out of the application. When I re-entered, I couldn't delete any search engines. How can I change my search engine in Opera to Google?
