### Issue Tracking Info

- [x] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

Start by reproducing the login failure in the iOS app on version 2025.6.0 with the reported iOS environment. Then trace the BitwardenShared stack trace and the reported Rust panic involving the Unicode character boundary. Done means login reaches the vault without this error and the regression is covered by an appropriate test.
