Made a thread about this issue with me, html 5 test results shows h.264 support is 'No' AAC support is 'Yes'

I thought I posted this reply to this, my mistake!

I installed Windows 11 fresh.

I am not dealing with a N version of Windows 11, it's just Windows 11 Pro, version 21H2. I tried playing a video through my browser from my computer a mp4 file and Opera Gx wouldn't play it.
