      Since the recent update (Opera 85.0.4341.60, windows 10), the PDF viewer does not work for me. For example, when I visit https://arxiv.org/pdf/2204.02984.pdf, it shows:

      47f0feae-18a3-4576-a13a-7bfdc1633a33-image.png

      I try to uninstall and reinstall opera, disable plugins and delete all the profiles, but no change.

      I try to install the older versions (including 81-84), the PDF viewers work fine.

      Any comments?
      Thank you in advance.

        @lintao51 Does it work in Chrome, Edge or any other Chromium based browser? What about non-Chromium browsers?

          Dear @leocg ,
          It works fine in following browsers (Windows):

          • Google Chrome 100.0.4896.75
          • Microsoft Edge 100.0.1185.36
          • Firefox 99.0

          According to this link, I also create a HTML file in local. Except the Opera 85, others work fine.

          I had tried to remove all the paths, including "Install", "Profile" and "Cache". But the problem still exists when using Opera 85.

          BTW: I also test with Opera 85 (macOS 10.14.6), the problem also exists.

          Thanks.

              Firtst Win+R then input
              %APPDATA%\Opera Software\Opera Stable\Local State
              open as notepad
              find in
              "location":{"country":"CN","country_from_server":"CN"}
