Null reference exception in Get-AzRoleDefinition

### Description

Running `Get-AzRoleDefinition` errors out in our tenant with:
`Object reference not set to an instance of an object` and no other explanation.

Suspecting a permission issue, still the null reference exception should be handled.
Running with v9.3.0 but reproes also with v10.1
