Passing Variable to Remote Computer with Invoke-Command and Get-CimInstance - powershell

Question

I've been attempting to pass a variable in Powershell using Invoke-Command, however, every example I've found doesn't seem to work when using Get-CimInstance. This is the basic code I'm using is:
$Computer = (Read-Host "Enter Computer Name")
$User = (Read-Host "Enter User Name")
$Cred = (Get-Credential -Message "Enter Credentials" )
Invoke-Command -ComputerName $Computer -Credential $Cred -ScriptBlock {(Get-CimInstance -Class Win32_UserProfile -Filter 'LocalPath like "%$User"').LocalPath.split('\')[-1] | Remove-CimInstance}
When I run that I get a null value:
You cannot call a method on a null-valued expression.
+ CategoryInfo : InvalidOperation: (:) [], RuntimeException
+ FullyQualifiedErrorId : InvokeMethodOnNull
+ PSComputerName : DBServer
I've also tried using the -ArgumentList flag, but that doesn't work either and I get the null value error again:
Invoke-Command -ComputerName $Computer -Credential $Cred -ScriptBlock {(Get-CimInstance -Class Win32_UserProfile -Filter 'LocalPath like "%$using:User"').LocalPath.split('\')[-1] | Remove-CimInstance} -ArgumentList $User
or:
Invoke-Command -ComputerName $Computer -Credential $Cred -ScriptBlock {(Get-CimInstance -Class Win32_UserProfile -Filter 'LocalPath like "%$args[0]"').LocalPath.split('\')[-1] | Remove-CimInstance} -ArgumentList $User
My best guess is that the -Filter flag is causing the issue. Though it works just fine if run locally. Also in my test case some usernames start with a dollar sign (ie $fredsmith) which may be an issue as well.

The doublequotes have to be on the outside to interpret the variable.
$user = 'joe'
"localpath like '%$user%'"
localpath like '%joe%'
This worked for me at an elevated prompt with the winrm service running:
invoke-command localhost {
get-wmiobject win32_userprofile -filter "localpath like '%$using:user%'" }
Or with no quoting issues:
invoke-command localhost {
get-ciminstance win32_userprofile | where localpath -match $using:user |
remove-ciminstance -whatif }
invoke-command localhost { param($user)
get-wmiobject win32_userprofile | where localpath -match $user } -args $user
invoke-command localhost {
get-wmiobject win32_userprofile | where localpath -match $args[0] } -args $user
