After the latest update (Version 81.0.4196.54), many tabs crash and after a few crashing tabs Opera closes completely.
I tried opening Opera from a terminal
When Opera closes, this is what I see in the terminal:
Crashing due to FD ownership violation:

Violación de segmento (`core' generado)
(Violación de segmento means segmentation fault)
Some sites crashes 100% of the times, like Whatsapp web, or my bank's website (www.bbva.com.ar). Some sites crashes most of the times when I interact with videos (like if I hover a video on twitter to show the controls to pause/play it it), but every now and then the controls work (YouTube, never crashed).
I tried in incognito mode in case any extension was causing this but sites keep crashing.
At first I suspected the problem was the libffmpeg.so fix that I have to run after every update that I got from this thread https://forums.opera.com/topic/37539/solving-the-problem-of-the-opera-browser-with-video-playback-in-ubuntu-and-similar-distributions-linux-mint-kde-neon, but websites like whatsapp web crashes immediately so I don't think it's related to videos.
I don't know what to try to debug this.
If it helps: I use Linux Mint 20.2, opera is installed through apt
