Persistent Error Message

STILL Cannot get rid of this error message that has appeared for many months. Is there any way to fix?

”Some iCloud Data Isn't Syncing. Your end-to-end encrypted data stored in iCloud can't be accessed on this device. It includes saved passwords and data from Health and Maps. Verify your account information to resume syncing.”

When I attempt to “Resume Data Sync” - it reverts/loops back to this same message.

Running iOS 17.4.1 on iPhone Xs

Updates iOS 17.7 and 18.0.1 are available, but updating never resolved this issue.

Thank you for any help!
