Original GitHub issue: https://github.com/bitwarden/android/issues/6503

Steps To Reproduce

  1. Install or update to Bitwarden Android 2026.1 RC (tested on rc45).
  2. Launch the app.
  3. Attempt to unlock the vault (master password unlock, possibly after using biometrics or PIN previously).
  4. App crashes immediately during the unlock process.

Note: Reproduction is not fully deterministic, but once the state is broken the crash occurs consistently.

Expected Result

The unlock flow should initialize all required unlock state (including MasterPasswordUnlock),
or gracefully recover by re-requesting credentials if local state is missing.
The app should not crash.

Actual Result

The app crashes during the unlock flow with a MissingPropertyException indicating that the
required MasterPasswordUnlock data property is missing.

Environment Details

  • App version: 2026.1.1 (21176)
  • Build: 2026.1-rc45
  • Commit: 0ee3e2e249
  • Device: vivo V2502A
  • Android version: 16

Clearing app data resolves the issue, which suggests incomplete or corrupted
local unlock state rather than account or server-side problems.

Issue Tracking Info

  • 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.
