Hi @ComputerHabit,
PnP PowerShell now needs PowerShell 7.2 or later. You can update your PowerShell version and see if the issue still persists. Generally, we discuss PnP PowerShell in GitHub here: https://github.com/pnp/powershell/issues. And if you have questions about SharePoint PnP PowerShell, we also welcome you to post in Microsoft Q&A and attach the SharePoint tag. We will help you as much as possible within our capabilities.
