PowerShell prompt for specific input then continue script

I'm stuck with this powershell script.

The script does the following:
When user presses y: 1.bat opens and runs for 3 second then closes.
Then the script asks the user if they want to run the 1.bat again, or when they press q the script NEEDS to continue, but the script ends

#Asks to start Password reset again if it fails
while($true) {
$readHostValue = Read-Host -Prompt "If Password reset fails enter y or q to continue install"

switch ($readHostValue) {
    'y' { Start-Process C:\Users\deniz\Desktop.bat -Verb RunAs }
    'q' { return # Ending password reset and continue script
        }
        Default { write-host "Invalid input y or n!" }
        }
    }

The script stops here, but needs to continue with the following:

#progress indicators/write-progress
Write-Progress -Activity "AfterLoader" -Status "Installing" -PercentComplete 10
Start-Sleep -Seconds 2

<!-- language-all: sh -->

As Rav's answer points out, return in the context of a switch statement's action block exits the enclosing function or script.

By contrast, break and - situationally^[1] - continue exit the switch statement only, which means that your indefinite loop (while ($true) { ... }) continues, unless you take additional action.

In this case you can take advantage of a rarely seen variant of the break statement, namely one that can target a labeled statement to break out of:

# Note the self-chosen "menu:" label
:menu while ($true) {

  $readHostValue = Read-Host -Prompt 'If Password reset fails enter y or q to continue install'
  
  switch ($readHostValue) {
    'y'     { "running things..." }
    'q'     { break menu } # Break out of "menu:" labeled while loop.
    default { Write-Host 'Invalid input y or q!' }
  }

}

'continuing...'

Alternatively, you could use a Boolean variable to determine when to exit the while loop:

$continue = $true
while ($continue) {

  $readHostValue = Read-Host -Prompt 'If Password reset fails enter y or q to continue install'
  
  switch ($readHostValue) {
    'y'     { "running things..." }
    'q'     { 
       $continue = $false # signal that the while loop should exit
       break              # break out of the switch statement
    } 
    default { Write-Host 'Invalid input y or q!' }
  }

}

'continuing...'

^{[1] With array-valued switch input, continue proceeds to the next element. If the input is a single object or a single-element array continue has the same effect as break, i.e. it exits the statement.}

Your return statement exit the entire script, not just the loop. That’s why your script stops there and does not execute the rest of the code.
