Failing to uninstall a module because "The website encountered an unexpected error. Please try again later."
The uninstall &amp; updated errors are like symptoms of the same problem; your profile module installation has corrupted DB storage so the module can't remove its DB tables, or retrieve its entity definitions to upgrade it.
You'll need to do a manual recovery on in a test environment so you can fully uninstall then reinstall so it has functional DB schema again. Manually restore the profile table (or any other DB schema) that the modules needs, then attempt uninstalling again. Repeat this process so you're able to successfully uninstall the module, then re-install it so it has a functional schema.
Once you've confirmed the process works, perform it on your live DB (after backing it up).
