[BUG] Deployment Issues with 500.13

**Describe the bug**

A few times I have come to deploy the API recently I've been getting 500.13 on the site.

After digging in the logs the error appears like something to do with accessing web.config and then runtime issues.

In both time this has happened I've proceeded into kudu and upgraded to the latest x86 version of the .NET runtime and Logging package and this has resolved the issue.

I protect deployment to production by upgrading first and this results in a seamless deployment .

Therefore there is something going wrong where the minor version of the installed runtime on the app service is causing 500.13 issues with my deployments.

**To Reproduce**

I expect wait until a minor upgrade of the .NET Core runtime
Don't upgrade it before app deployment
Attempt deployment
Watch the staging site fall over.

**Expected behavior**
Minor version changes shouldn't negatively impact runtime

**Additional context**

We need to look at the API build mechanism to see if there is anything we can do to avoid this.
