Unbelievably High Memory Usage

I haven´t made any major changes to Opera, except adding three wallet extensions.

I also experience that some pages, especially live streams on Youtube, stop working - if I put the address in a new tab, it works again.

I have experienced this with many tabs before, so I try to keep it down to 20-30, and that´s been fine forever.

One thing that may be different is I have had many AI pages open, but the problem persists even if I reboot and close those tabs.

When I look in Computer Management it says 38 processes on Opera, and I did get an update notice, but that´s days ago now, and I have had this problem for almost a week now.

Do you have any clue at all ?

I use Opera because it´s the fastest, mainly, and for the mouse movements. Now I have all my cookies and everything here. I can´t change now. Can I download a different version and load the bookmarks, extensions and the cookies?

What is going on here? Even as I type this, I have eight tabs open, one of which is a live stream and two AI-pages, and the letters are lagging behind as I type.
