SwisPowerShell 3.2.0.50049 is incompatible with VMWare.PowerCli in PS7

[fullenw1]

Both were working just fine until I upgraded SwisPowerShell to version 3.2.0.50049.

Now, if I load SwisPowerShell first I cannot load VMWare.PowerCli anymore.
And if I load VMWare.PowerCli first, then the Connect-Swis cmdlet returns an error.

This behavior only appears in a PowerShell 7 host (7.3.6 precisely in my case).

Loading SwisPowerShell first

PS> Connect-Swis -Hostname $OrionDatabaseServer -Credential $OrionCred

Troubleshooting

What is strange is that even after unloading the other module, the issue still remains in both cases.

As a workaround, downgrading SwisPowerShell to version 3.1.0.343 fixes the issue.

I noticed this behavior only in a PS7 host.
So using a PowerShell 5.1 host can be another workaround.
