@burnout426 hello, thank you very much, it seems you are absolutely right, I had Kaspersky installed, after disabling it, on those sites where I reproduced the "endless loading" problem, everything started working as correctly as on Chrome, which is strange because Kaspersky should have had the same effect on Chrome and Opera, and this was misleading. It is unclear why such a problem occurs in combination with Kaspersky and Opera.

@TycheSD said in Opera Browser Not Loading Web Pages Properly on Windows:

@aleksr2 Hi, I ended up uninstalling Opera and then reinstalled it. The version I had apparently couldn't be updated normally. I haven't had any problems since then.

Hi, no, unfortunately even a complete uninstall did not fix the problem for me. I completely uninstalled Opera, along with user data (user folders and cache), rebooted the PC and installed the latest version of Opera from scratch, after that I went to a site where I can easily reproduce the problem with endless loading and it repeated again on a completely clean browser without any data, based on which I conclude that the reason is in the browser itself. Google Chrome works correctly on the same sites.

The same problem appeared at the end of 2024 and is still not solved for me, the latest updates did not solve it. Disabling extensions did not help, I tried to enable and disable different flags related to cookies, did not help, DNS over HTTPS was disabled for me initially, a very incomprehensible problem, makes me leave Opera. As was said above, the problem with endless loading can be easily provoked if you use the search form inside sites like Amazon Aliexpress, etc., but even without this, sites often refuse to load, while in other browsers everything works perfectly.
