[Bug] DuckDuckGo won't start (crashes every time)

[2011]

Describe the bug

When I attempt to start DuckDuckGo, I see a black screen for a few seconds, and then the display goes back to the launcher.

How to Reproduce

Just press the DuckDuckGo icon and always get the behavior described above.

I do have logs, which I hope will indicate the problem:

Based on the logs I think the issue is with the local database versioning, Try clearing the app's storage and relaunching it.
