Reset end to end encryption loop

I have a very frustrating issue about my iCloud, I keep getting notification in settings to update my Apple ID and when I try to update it, it asks me to enter my Apple account password, after that it ask me to reset end-to-end encryption data, I press continue, then nothing changes and I get back to beginning like nothing happened, and the notification still world exist and didn’t disappear, I tried to reset all settings manually, but the notification still there!!

now I can’t sync keychain and my AirTag is not recognized by my phone, and I keep getting notifications “someone is following you” 😖, and any service that use end to end encryption.

I have this issue for more than 2 months, I went to Apple Store didn’t help, I called Apple support, after one week of work with them, they told me it’s just you, this is general issue and it will be fixed with an update, I got since this problem 3 updates and still the same problem, my AirTag is useless and actually annoying because of the “security alert” (someone is following you).

any suggestions?
