@VitPavelka That’s some seriously good troubleshooting. Since you can reproduce the crash just by restoring that rich_wallpapers.selected_id, I’d say you’ve isolated the problem pretty well.

I’d definitely include those exact steps and the before/after selected_id values in the bug report. Opera’s 136.0.6008.52 release did include crash fixes, but the published changelog doesn’t mention this wallpaper/profile issue, so your reproduction case could be really useful to them.

For now, changing it back to bundled/default sounds like the sensible workaround.

Yep I had the same issue and I just uninstalled Opera and Re-installed it and it worked. I tried just re-installing the browser without wiping data and without uninstalling and nothing was working so I just went nuclear and wiped everything. Now it is working again.

@pindos Hi Pindos, thanks a million for your reply! I will look into it right now.

Thanks again!

Feel free to install version 127.

Unfortunately 128. had to be withdraw until it will be more stable.

Just to add to the list: I saw the same error with "chrome/browser/process_singleton_posix" when updating to 125.0.5729.12 on Ubuntu. I "fixed" it based on @zibi1981 suggestion above, as follows:

From my crude understanding, it would again point to wayland vs x11 issue, but anyway, just sharing in case someone else ends up here after seeing opera crash on startup in Ubuntu.

@leocg the beta works thank you. I don't know why the non beta version crashed on me all the time tho. Thank you

I have the exact same problem with Opera GX, happens also with Twitch.
