I've tried installing the latest version of Az multiple times with the same result.

@briancuster What location are you install Az into? Can you try installing AZ into C:\Program Files\PowerShell\Modules or at least not into the same folder as AzureRM? I'm not sure if that is the issue, since the output is clipped. If you installed AzureRM into C:\Program Files\PowerShell\Modules try running Uninstall-AzureRm so you don't have those SxS with AZ?
If you want AzureRM and AZ both on the same machine, the best way is to use Azure RM in 5.x and Az in 6.x.

@briancuster This looks like an incompatibility between the PackageManagement and PowerShellGet modules, which can be tricky to extricate yourself from. Have you tried updating your PowerShellGet module (Install-Module PowerShellGet -Force).

Closing due lack of activity

Well ...

PS C:\> Install-Module PowerShellGet -Repository 'PSGallery' -Force
PackageManagement\Install-Package : Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

Finally figured this out. The problem is with previous package metadata. Manually deleting the Az-subdirectories solved the problem. Now 3.1.0 installs without problems.

@HQJaTu do you recall what was the exact issue with the metadata?
Having it right now with a custom written module, struggling to narrow down the issue.

Unfortunately no. I have no idea about the exact nature of the problem.
I was trying to get a server setup done and was focused on getting results. Deleting all the already installed Az-modules and reinstalling solved it.

All good, thanks for sharing @HQJaTu

In my case, it was a combination of broken scripts in the module and maybe incorrect versioning. Works well but now I am stuck with packaging module with sub-folders for ps core - looks like dotnet nuget hangs the packaging process in some cases:
