[Support] Safari issue after updating to macOS Sonoma

Hi!

I recently updated from macOS Monterey to macOS Sonoma, and I'm experiencing a bug that's driving me crazy.

I like to browse in Private Browsing so I don't have to deal with browser history, but I also like to manage my tabs manually, so I have "Safari opens with:" set to "All windows from last session".

My problem is that Safari opens my old tabs and a new empty one (didn't happen in Monterey), which I have to close manually. It's getting annoying. Does anyone know if there's a fix for it, or do I have to live with it?

Thanks in advance.
