Hi,

I recently decided to try Opera out and I really like it overall. I have a problem that i can't crack. On the chessable.com web site, the section for online classrooms does not load. I'm not talking about the main presentation page (https://www.chessable.com/getclassroom/) but the actual classrooms (for example this one).
It should look something like this

Instead all I get is the background (white if it's in normal mode and gray if it's in dark mode).

I tried evertything I could think of but it always goes to that blank page. The same page works just fine on Opera Mobile for Android for example, and on Brave, both the Windows and Mobile versions.

I use windows 11, Opera version: 120.0.6099.268

I tried disabling the adblocker and traker blocker and all other extensions, disabling the antivirus software, reseting all the data in opera even installing operaGX. No result. Just the same background page.

Do any of you guys know what the issue might be?

Thanks in advance.
