[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.

I tried that. I saw the initial setup, but after I completed it, the app died. When I attempt to start it now, I do see a blankpage for a fraction of a second before the app dies (it died immediately before). I do have new logs:

@2011 Can you check the version of the system webview on your device and let us know? It should be the same as Chrome's version.
Open Chrome browser, go to "Settings", scroll down and select "About Chrome". You should see there the "Application version".
