• Verified the test plan from [Android] fix crash brave rewards onboarding country selection brave-core#16341 (comment).
• Reproduced the issue using device above and version 1.46.138.
• Verified that when using 1.46.143, the browser did not crash when tapping on the list of countries from the rewards panel. Confirmed able to select my country (US), and join Rewards. Was presented with onboarding tour and "first ad" as expected.
• Confirmed this worked for clean profile without issue.
• For upgrades, one upgrade case worked, the other did not.

Upgrade Case 1 - FAILED, follow up issue logged

1. Install 1.46.138
2. Reproduce crash
3. Upgrade to 1.46.143
4. Tap on rewards icon
   --> no country selection/onboarding. Panel looks odd. brave://rewards-internals shows "no wallet created". Appears as though rewards is in some kind of borked state. Close/reopen panel, close/reopen app - none of this resolves the issue and brings up country selection/onboarding.
