On "Yandex Images" search: "Content scripts are not allowed on this page". What is does it mean? 3 weeks ago work properly, but now is error (don't working)

On "Opera GX" (latest version) is doesn't work now. Why? Please answer

Please make it so that the results page opens in the local language, not English, for example, so that Yandex does not have ENG (language), but the local language (for example, RU (Russian));
