So I'll post the main things here :
Issue: I am unable to watch any sort of media on Opera GX, except for Youtube. Everything else, keeps telling me I don't have a supported browser, or it's out of date. ( In exampe : Netflix, Hulu, Prime Video, Twitch. )
Version of Opera Gx: 78
Windows: Windows 11 Pro ( Browsers read it as Windows 10.0 NT )
HTML5 Test reads that my browser does not support H.264, H.265, or MPEG. Supports AAC.
Trouble shooting steps I've tried, : Resetting OperaGX to default, uninstalling and reinstalling OperaGX. Turning off Hardware accelerator both in flags and system, turning them back on. Turned off all ad blockers. Messed with Opera://compononets as Netflix stated I needed to go there to make sure it's up to date ( it is ).
This issue sprang up after I installed 2 new drives to my PC and removed my old HDD.
I old storage layout was :
M.,2 = Windows, and all the browsers and important stuff,
HDD: Games and extra storage.
I removed the HDD and ever since then I've been having these issues and my HDD is wiped already. Not only that but games as well have been issues that I had to fix so I'm uncertain as to what was even in my HDD that would cause all these things to stop working.
Any help would be appreciated as I don't wanna use Chrome, since Chrome is the only browser that works for me right now lol
Also, Windows Media Feature pack does not show up at all for Windows 11, so there is no way for me to get it.
