You might not want to do this, but I don't see how it could be dangerous...

If you go to the application info in your settings, and clear the cache and data, it's like a fresh reinstall. I'm assuming you'll have to re-log in, but if you use something like amber, then that should be trivial.

I think the only thing you would lose is the state the app was in before the crash loop which the only reason you'd want to keep I assume is so that you can accurately report on it but since you can't...?
