Since yesterday, for now apparent reason I can't use Opera anymore. When I launch it, it freezes indefinitely. I can force kill it, it works sometime but sometime a process stay active and can't be killed.
I have no idea what caused this. The browser was opened for a couple of hours and suddenly it just stopped working.

What I attempted so far :

• Restart computer
• Run as administrator
• Uninstall/Reinstall the latest version, and even older versions
• Delete the folders from /Local and /Roaming, then uninstall and restart the computer. Install it again, same issue.
• Sacrifice a chicken
• Cleaned data and registry with CCLeaner
• Antivirus check using Adware cleaner
• Latest windows update (the issue happened before I updated)

My gear :

• Windows 10
• Opera latest version (must be 53)
• I do not run a tier antivirus software, just Win Defender

Any clue ?

Thanks
