Opera Browser not closing

Trying to clean, but CCleaner states Opera Browser is not closed and then tries to force close it, but to no avail. Goes on for hours. What is the issue and how can it be fixed? it was working fine just yesterday.

After closing opera open task manager, if you find any opera remnants end them. If they're hanging around something is keeping it open usually with browsers this is because an addon (does opera have addons idk) or a cloud service such as sync or a print service.

Tried that Negal, did not work. Opera was not running in the task manager.
