Extension stopped after accidentally enabling Google Enhanced Protection (even after I turned it off)

[wtw11mdg]

As mentioned in the title, Google pops up a notification asking me to turn on the Enhanced Protection feature (I think that's what it's called in English; in Chinese, it's "強化防護").

After that. I found that Google blocks Fadblock and said that the extension is not safe. So I try to disable the Enhanced Protection.
But after that, whether I turn on or off the feature Fadblock never works again.
I already tried to log out of YT and delete all cookies or reinstall Fadblock, but everything does not work.

Did anyone experience the same problem?

Not sure if it's related, but Opera flagged it as malicious for me just this morning...
