Hi Anthony Conrad,
I've been able to avoid the error.
Here the correct commands:
Add-Type -Path "C:...\MyProvider.dll"
$handler = New-PnPExtensibilityHandlerObject -Assembly "MyProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" -type "MyProvider.ListsProvider"
Get-PnPProvisioningTemplate -Out test.xml -ExtensibilityHandlers $handler
