Drives will be unmapped if Membership could not retrieved

[IntuneEnterPriseAdmin]

Hello,

if the Script runs (offline, or with no active VPN connection) the Script does not retrieve the GroupMemberships and unmapp all drives
with active GroupFilter.

$groupMemberships = Get-ADGroupMembership -UserPrincipalName $(whoami -upn)

this will return nothing

for me i changed it to

if(!$groupMemberships)
{
Write-Output "No GroupMemberships, exit Script"
exit
}

so if no GroupMemberships can be retrieved it stops the processing and does not unmapp my Drives.

ps. failure handling in this part is also important

catch {
#nothing we can do
exit
}

Thank you
