How to immediately close all Internet connections just for qBittorrent using a script? (windows)

[GitHubinatrix]

I have this A-OK working PS1 script

# Get the list of network adapters AKA network interface cards
$LIST_OF_NETWORK_ADAPTERS = Get-NetAdapter

# Disable all network adapters
$LIST_OF_NETWORK_ADAPTERS | ForEach-Object `
    {
    Disable-NetAdapter -Name $_.Name -Confirm:$false
  # Enable-NetAdapter -Name $_.Name -Confirm:$false
    Write-Host "Disabled adapter '$($_.Name)'"
    }

Read-Host

which quickly disables Internet on my system. But I want to cut off network access just for qBittorent, so that I can with one click make the whole bandwidth be made available for whatever that I may need it for [and then with a counterpart script re-enable Internet access for qBittorrent whenever I will be ready]. Unfortunately so far I have been unsuccessful as e.g. this script

# Define the path to the program executable
$ProgramPath = "C:\qBittorrent\qbittorrent.exe"

# Define the rule name
$RuleName = "BlockInternetForProgram"

# Check if the rule already exists, and if it does, disable it
$existingRule = Get-NetFirewallRule -DisplayName $RuleName -ErrorAction SilentlyContinue
if ($existingRule -ne $null) {
    Disable-NetFirewallRule -Name $RuleName
}

# Create a new outbound rule to block internet access for the program
New-NetFirewallRule -DisplayName $RuleName -Direction Outbound -Program $ProgramPath -Action Block

Write-Host "Internet has been blocked for: $ProgramPath"

Read-Host

produces in PowerShell window this error

New-NetFirewallRule : There are no more endpoints available from the endpoint mapper.

Is there a way to tackle just qBittorrent using PS1, BAT or VBS? Or AHK maybe?

can you use "netsh" to open and close the specific inbound/outbound tcp/udp ports that qBittorrent uses?

Alternatively, in Windows you could create a virtual network adapter that is tied to your physical adapter - then in the qBittorrent advanced settings, you can force it to only use the virtual adatper. This way it's only a matter of enabling/disabling the viirtual adapter through a PowerShell script.

But would not dynamic nature of port assignments and the constant changes in network connections make it difficult to maintain such a broad and static block effectively when using netsh?

I mean: today it works, but tomorrow it once again might stop - thus I will be forced to bother with checking my localports numbers and then adjusting my script?

Well? Can anyone comment on my findings?
