Add-PnPClientSideWebPart : One or more errors occurred.

Ran my script like this to login:
#Connect to PnP Online
Connect-PnPOnline -Url $SiteURL -interactive

Delete/Remove all versions of PnpSharePoint version as
pnp.powershell has replace those deprecated version, https://pnp.github.io/powershell/.

Get-Module -Name *SharePointPnP* -ListAvailable | Select *
Uninstall-Module SharePointPnPPowerShellOnline -Force –AllVersions (This did not work. So I found the path in the first output and deleted.)
Find the path it is located. Mine was located here C:\Users\USERAccount\AppData\Local\Apps (I did leave the 2.0 folder)
