300 tabs disappeared from my iPhone while in private browsing mode.

On September 4, 2026, all 300+ Safari tabs I had in private browsing mode disappeared. I didn't close them, and there was plenty of space on my device. Earlier that day, everything was fine, but when I opened the browser again, they were gone. There are no history or bookmarks. Has anyone encountered this? How can I recover it? Is it possible? I recently had 100-200 MB of free space on my device, and all my new tabs, both in private browsing mode and in regular browsing mode, closed. Why does the system allow this? This is the first time this has happened. Russian-speaking phone support can't fix the problem. Please help!
