This post is "for your Information", rather than seeking help;

For the third time now I've experienced, out of the blue, "Opera not responding" a couple of seconds after opening.
Checking resources via Task Manager, shows High CPU & Memory usage and Very High Power.

This last time, I downloaded the latest version and upgraded, to no effect.

Correlation with my vague memories of the past, I think in each case, the cause has been the same.
Win10 64 bit has updated in the background, silently and without my knowledge, and has been sitting awaiting a re-start.
Even at this point, before the restart, Opera freezes, just giving the options to wait or close, (if indeed this popup appears at all; sometimes I need to use Task Manager to End Task). After the re-start, there is no improvement; and changing various Opera, or Windows, settings makes no difference.

I've now found that just allowing Opera to Wait, it eventually kicks back into life. The PC can be used with a different browser whilst you're waiting, and functions normally with other programs; albeit a little slower.

N.B. don't be impatient, I've had to leave the PC turned on, with Opera consuming lots of resources, for upwards of 3 hours, and once overnight. It does however eventually sort itself out.

I'm not telling you to do anything.

For someone having the problem of Opera freezing during and after a W10 upgrade, it provides a solution, albeit a slow one.
Have you any better ideas for next time I have the problem??

@AnthG don't know if you're still monitoring this thread.
When I had this problem, I just let Opera " wait for program to respond" rather than "end program"
Be patient, it can take several hours, or even overnight.

@windbags Have you tried peak4's "solution"?

I had sync disabled since the update but I just tried signing in again and it worked for me, too! "Several hours" seems a bit extreme but I did have to wait 5 minutes on a sluggish laptop and 1–2 minutes on a less sluggish desktop PC for Opera to respond again. After that I was logged in and everything had been synced.

It may well depend on how many tabs you have open at the time it hung.
For various reasons, and it never normally causes issues, I was probably running with 100+ open at the same time,

I had a few tabs, as I always have several "tasks in progress" that need the info, but nothing like that many. I did try removing ones I thought I could easily retrieve, but after three goes I was getting fed up of it "not responding".
Waiting for minutes/hours/overnight on the "hope" of eventually getting a response is not the mark of a useful browser - especially when Windows 10 updates keeps forcing me to restart the system.

I've had the problem three times now, and in each case, it's when Windows has decided to do a major update in the background without telling me.
It's almost as though Opera is using a file in Windows, which the update changes on the fly, and then Opera gets its knickers in a twist.
Maybe because I normally have so many tabs open, otherwise without issue, the file update causes something to re-sync which then fails.
even when I save all open tabs to a speed dial folder, it doesn't take long, maybe a couple of minutes at most.
It's also noticeable that when Windows is updating itself, Opera Crash Reporter (or whatever it's called) itself crashes.

I've not tried it yet, but the latest version of opera has something called Workspaces available as a plugin or something, which might let me organise things differently.

I have a strange one here, on an up to date version of Opera, running on an up to date Win10 pro installation.

I have a number of different photo albums on Facebook, two of which won't allow me to add any more photos from my hard drive. When I click the "add photo" icon, it allows me to point to the relevant photo(s) in a folder, and select them, but won't add them to the album.

It doesn't seem to be a Facebook problem, as I can add photos to these same albums using Chrome, Firefox, Avast browser or Maxathon. Also I can upload to other albums, on the same FB account, using Opera successfully.

I've tried clearing cache and FB cookies in Opera; any other suggestions would be most welcome
Thanks
