<![CDATA[Can't launch Opera, clean installation or admin account didn't help]]>Hello everyone. I cannot launch Opera 106 64-bit on a latest Windows 10 22H2 build.

It haven't been used for a while (actually it's my sister-in-law's PC).

After updating Windows from 21H2 I tried to launch the browser but I got only black square, then a biiger white square, three of four times, then nothing.

I wiped out the browser with the user data, made a fresh install with the standalone installer, changing the 32-bit version with a 64-bit, launched it as administrator, launched it from Administrator account, but I get the same. The disk check, as well as sfc /scannow and dism, were performed. No errors shown in Event Logger.

I enabled logging but I don't know how to properly read the log file.

What I noticed was:

[5380:4576:0124/150938.342:ERROR:gl_display.cc(515)] EGL Driver message (Error) eglCreateContext: Requested GLES version (3.0) is greater than max supported (2, 0).

Any help would be appreciated.

After I reinstalled Opera I tried --disable-gpu again and it worked! Maybe I should have tried that twice yesterday. Thank you so much!..

I chose opengl in the flag, and I see that hardware acceleration is turned off. Should I try to find an option where it's on or leave it as it is?

Then try reinstalling. That more-thorough uninstall might help. Not sure though, but worth a try.

I enabled logging

Can you enable logging for a test standalone installation to a folder named "Opera Test" on your desktop?

In the log you provided, there are some signs of profile write permission errors, but you said you tried a standalone installation too. Would be interesting to see if those same errors happen there too or not.

I assume that if the Administrator account didn't make it, no user account might.

I wouldn't assume and would check just to make sure. It might not be a permission issue and could be something else.

I only have Windows Defender

Did you check the Smart App Control settings in Windows Security to make sure it's off?

Try turning off all the options in the Reputation-based protection section in Windows Security too to test if that helps.

I only have local accounts. The machine was initially instaled with the Microsoft account 4 years ago, MS Office is shared with this account on another machine, but this account doesn't function there for a very long time.

If so, you know it's something messed up with the existing accounts.

"C:\Users\yourusername\AppData\Local\Programs\Opera\launcher.exe" --disable-gpu

to test if that works. If so, you can adjust the Angle flag for your GPU to test if it helps (once you restart Opera normally). Or, you can disable hardware acceleration at the URL opera://settings/system.
