Perhaps upgrading to the newer pnp.powershell module is an idea? https://www.sharepointdiary.com/2021/02/how-to-install-pnp-powershell-module-for-sharepoint-online.html Has the same commands, when running the older just now it said to uninstall the old version (uninstall-Module -Name SharePointPnPPowerShellOnline -AllVersions -Force) and use install-module pnp.powershell

Or did you already use pnp.powershell?
