The phishing warning is not for your site, but for (ironically) the page your site redirects to because it’s suspended. It’s a false positive, and a known issue. As for the suspension itself, please refer to the following article. Nobody on the forum can help you with a suspension.
And for future reference, please avoid using AI to write your forum posts (besides machine translation anyway). It actually makes things less clear than if you had written the message entirely yourself.
And finally, if your site is that important, I would highly recommend making backups of it yourself after every change, or working on it locally.
