@burnout426 Thank you so much.

For those that it could help, I will do a Windows system restore, the last backup of which dates back to 3 days, which will allow me to recover my Opera session from that moment.

Or, a more simple way.
After crash, after you've started Opera and encountered an empty new session, while Opera is open, do a back-up of this folder -> %AppData%\Opera Software\Opera Stable\Sessions
Then you can close Opera, rename/delete current "Sessions" folder, and replace it the one from backup. Keep the backup until you will have a recovered session. Make sure in current "Sessions" folder is only by one "Session_####" and "Tabs_####" file (the smallest one can be deleted).

Important: When you notice that your session was lost, do not start browsing in this new empty session to not overwrite your old main session. For browsing Internet use another browser, another device, or a private windows in Opera (Ctrl+Shift+N).

Version:85.0.4341.60 (x86_64)
System:macOS Version 11.6.5 (Build 20G527) 11.6.5 x86_64

Crashes instantly if I am online, if I turn wifi OFF, it's fine. All extensions are disabled.

So frustrating 😞 Being on older macOS doesn't help either.

PS: If I go offline, open a Private window, close the main and go back online. It works fine. It crashes instantly if I open a new main tab.

Me too, it started 2 days ago. My opera crashes everytime i try to pinboard any page. Good it has autosave session, so none of my tabs got lost

@sagerhoninx96 Opera GX for Mac or Windows?

Can you get Opera to crash again? If so, does it do it when clicking the key for all sites or just for a certain site? Do you have Opera Sync enabled?

@fornit
Immediately after crash, backup %Appdata%\Opera Software\Opera Stable\Sessions folder contents (there is usually two sets of Tabs and Sessions files).
If Opera starts empty then, close it, remove this folder contents and copy there oldest (or biggest, should be the same) Tabs and Sessions files pair from backup

@leocg it could run for about 5 seconds, then close.

Install SessionBuddy.

Never lose your open tabs again. I learned this lesson not to trust Opera correctly shutting down a while ago

It's a Chrome extension so you need the Opera extension that allows you to install Chrome extensions.

Is it normal for your system to shut itself down after a slight freeze? And on top of that, no possibility of resuming the tabs that have closed because of this very annoying bug, 10 times in a month that it happens to me, it's really annoying. Put a session restore system!!

Thank you for the informative question and admin for the valuable answer. I am also looking to save my bookmarks and I am also afraid to lose them.

Was having a similiar issue, and this fixed it. Seems the easy file feature has a conflict with windows explorer. Anytime I tried to upload a file to any website, facebook, email, dropbox, youtube, etc. When I got to the step where windows explorer would normally open and allow me to select a file Opera and Opera GX both would freeze, unable to switch tabs or close the Opera windows/tabs. Also would occur when trying to save/download any files that required the windows explorer to open to select a file location.

Turning off easy files fixed this issue for me.

@quik Yes my system can handle it because when the animated background is loaded i can re-open a new tab and it doesn't freeze, but if i stay on the same tab for a while, when i open a new tab i have the problem again! I think they should preload the animated background at the start of OperaGX instead of at the opening of the tab! And i'll try next days without the animated background and comeback here to say if the problem persists!
