Just in case you didn't try this specific method:
Close Opera, open a command prompt and start Opera like this:
"C:\Users\yourusername\AppData\Local\Programs\Opera\opera.exe" "--user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36"
Then, goto the URL opera://browserjs and disable browser js for the session.
Then, goto the URL opera://settings/content/all, type adobe.com in the search field and click "Delete displayed data".
Then, turn off Opera's adblocking and tracking protection at the URL opera://settings/privacyProtection.
Then, turn off Lucid Mode at the URL opera://settings/lucidMode.
Then, goto Adobe and try things.
