I read that there is a flag that needs to be enabled, but I do not know which specific flag is.

Those services work fine on Chrome, Firefox, and Edge.

Print screen of the Error Code here (Imgur).

The only other thing I can suggest is to try in Opera Developer just to see if it works there.

If you feel like sharing your HBO login info with Opera via a bug report, someone at Opera might be able to investigate further.

These type of questions require some info up front.

What version of Opera?
71.0.3770.441

Is it regular Opera or Opera GX?
GX

What version of Windows?
Windows 10 Home 64 bit version 20H2

Is that version an "N" edition of Windows? If so, you might need to install the Windows Media Feature Pack for your OS.
No

At https://html5test.com/, does it say "Yes" for h.264 support and "Yes" for AAC support?
Yes

At https://bitmovin.com/demos/drm, does it say "Detected, using Widevine" above the video and does the video play? For MSE below the video, does it have "video/mp4; codecs="avc1.42c00d" checked? In the EME section, does is "Widevine" checked?
Yes

Did you try installing https://addons.opera.com/en/extensions/details/user-agent-switcher-5/ and setting the site to mask as "Chrome for Windows" (including editing the "Chrome for Windows" string to be Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.61 Safari/537.36)?
Yes

Did you try going to the URL opera://flags/#disable-accelerated-video-decode, disabling the flag and restarting Opera?
Yes

Did you try going to the URL opera://settings/system, disabling hardware acceleration and restarting Opera?
Yes

None of these have worked for me and I'm not sure what to do.

Now when I load the site it simply blocks me from entering at all, even with the user agent switcher.

Really obnoxious web design. Hope there's some other workaround possible.
