mp4 videos not showing on page after recent updates

After recent Opera updates, with adblocker still enabled and without exceptions added, legit mp4 videos are no more loaded and displayed on page.
Even with the site added to exception list, I get an unwanted behaviour:

• the legit video is finally loaded and can be played after several page refreshes
• the sound of legit video is muted (I have to unmute it manually)
• the page is populated with mixed frames of advertising (some displayed and playing, some black / masked)
• when scrolling down the page, even if the legit video is ended or manually stopped, a popup with the video appears on right bottom of the page and plays again (with sound), which is unwanted and annoying

Before the recent updates, with adblocker enabled and without exceptions added, all was ok (legit video loaded and playing (with manual start - no autostart) and no advertising on page).

Windows version: Windows 11 Home 25H2 (26200.7840)
Opera version: Opera One (128.0.5807.52)
Chromium version: 143.0.7499.194
Example site (which I have to add to exceptions): https://stirileprotv.ro/
Example pages:
https://stirileprotv.ro/stiri/ilikeit/inventii-surprinzatoare-la-ces-de-la-frigiderul-care-citeste-retete-pana-la-prosopul-smart.html
https://stirileprotv.ro/stiri/ilikeit/project-zomboid-unul-dintre-cele-mai-complexe-jocuri-de-supravietuire-unde-fiecare-decizie-conteaza.html

Hope you can help.

Just performed the latest update (Opera One: 128.0.5807.66 / Chromium: 144.0.7559.173). The problem persist.
So, I understand that after the recent updates the adblocker is broken. Could it be reverted to the previous (working) version, until the problem is solved?

@misterrr Thanks for all the details.
We'll need to consult this case internally and get back to you.

@misterrr I got an error message both in Opera and Chrome.

@leocg Sorry, I didn't see any error message. Could you be more explicit?

Just performed the latest update (Opera One: 128.0.5807.77 / Chromium: 144.0.7559.173). The problem persist (the adblocker is still broken), but with no error message.

@misterrr Just checked again.

With ad blocker on: video doesn't even show, its space is blank. With ad blocker off, I got a Media Element Error: Format Error message

That same message appears when I open the page on Chrome.

@leocg I said in the first message:

• with adblocker on: instead of video I get a black frame with no video:

• with adblocker off: I get no error, the video plays but with unwanted behaviour.

I tested now with Opera 127.0.5778.76 and it works ok, as expected (as before update to 128).

So, definitely Opera 128 is broken and should be withdrawn until solved.

@leocg I would like to mention that I tested also in Chrome, Edge and Firefox. Video loads ok, with no error.
