'DB Error - No Such Table' — CiviCase in Drupal 7

Question

I have a Drupal 7 + CiviCRM database with CiviCase. This is a fairly new install. I would say CiviCRM was installed fresh about 3-4 months ago. As of now, CiviCRM has been upgraded to the latest current version, 5.25.0.

I noticed the following problem on 5.24, but as this is still a new install in development, its possible the problem has been there since the beginning.

When I go to Cases -> Dashboard, I see:

DB Error: no such table

Additionally, when I go to view a Contact, and then click the "Cases" tab, I see the follow message in the upper right of the screen:

Unable to reach the server. Please refresh this page in your browser and try again.

How should I go about fixing this? It seems like the entire table structure is missing?

There is no production data in the CiviCase extension yet, so if it is possible to just do a complete fresh install of just that portion of CiviCRM, I can do that. I just don't know how I would do that safely without affecting the work I've done to other portions of the Drupal and CiviCRM database.

Here is the backtrace for when I see the DB error:

As confirmed in chat the views hadn't been created and disabling and reenabling civicase at Administer - System Settings - Components fixed it.
