Is it safe to uninstall and reinstall Azure AD Connector if I have exported the config?

Question

I have a multi-connector setup and a couple of the connectors are getting password hash sync issues. Error 611. However, removing and reenabling PHS isn't working. Azure AD Connector is version 2.2.1.0

Also using the below script isn't working gives me an error.

Script

Import-Module adsync
$adConnector = "Domain name"
$aadConnector = "extensible2 name"
$c = Get-ADSyncConnector -Name $adConnector
$p = New-Object Microsoft.IdentityManagement.PowerShell.
        ObjectModel.ConfigurationParameter `
        "Microsoft.Synchronize.ForceFullPasswordSync", `
    String, ConnectorGlobal, $null, $null, $null
$p.Value = 1
$c.GlobalParameters.Remove($p.Name)
$c.GlobalParameters.Add($p)
$c = Add-ADSyncConnector -Connector $c
# Disable password sync through Azure AD Connect
Set-ADSyncAADPasswordSyncConfiguration `
    -SourceConnector $adConnector `
    -TargetConnector $aadConnector -Enable $false
# Enable synchronization and run the full password hash sync
Set-ADSyncAADPasswordSyncConfiguration `
    -SourceConnector $adConnector `
    -TargetConnector $aadConnector -Enable $true

Error:
