PowerShell works only when running in a console and not as a PS1 executable file

I am fairly new to PowerShell and am having challenges trying to get a PS1 executable file to work. Running the script in a PowerShell console works completely fine and copy's items and creates the correct log filename.

The expectation would be to Right-click the PS1 file containing the script, run the script with "Run with PowerShell", and then allow the script to finish with a log file populated and files copied when user prompt selects yes.

At this point, there are no errors messages, other than the PS1 file script gets replaced by ton of unrecognizable symbols/characters and creates the log file as "Box Project Files.ps1JobFileLocations.log" instead of "JobFileLocations.log".

The PowerShell version being used is 5.1. Windows 10 OS. Set-ExecutionPolicy was set to Unrestricted and confirmed as Unrestricted for CurrentUser and LocalMachine. Unblock-File was also tried.

Below is the script that works in a PowerShell Console but not as a PS1 executable file.

# Drawing Tag Searches
$MechDWGFilterList = @('*IFC*','*mech*', '*permit*', '*final*')
$DatabaseFilterList = @('*field*','*software*')

# Root folder and destination folder
$JobNumber = '*'+(Read-Host -Prompt 'Enter in job number')+'*'
$srcRoot = 'C:\Users\username\Box\'
$JobRoot = (Get-ChildItem -Path $srcRoot -Filter "*Active Projects*" -Recurse -Directory -Depth 1).Fullname
$dstRoot = $MyInvocation.MyCommand.Path
# Find job numer pdf file
$JobFolder = (Get-ChildItem -Path $JobRoot -Filter "$JobNumber" -Recurse -Directory -Depth 0).Fullname
$Logfile = $dstRoot+"JobFileLocations.log"

$reply = Read-Host -Prompt "Make a copy of relevant project files to local drive?[y/n]"


# Find sub-folder from job folder
$ProposalFolder = (Get-ChildItem -Path $JobFolder -Filter "*Proposals*" -Recurse -Directory).Fullname

}

    # Where the file name contains one of these filters
    foreach($filter in $MechDWGFilterList)
    {
        if($file.Name -like $filter)
        {
            LogWrite $file.FullName
            if ( $reply -match "[yY]" ) 
            { 
                Copy-Item -Path $($file.FullName) -Destination $dstRoot

    }
}

LogWrite "`n-------------------Database-------------------"
foreach ($file in $DatabaseList)
{
    LogWrite $file.FullName
    if ( $reply -match "[yY]" ) 
    { 
        Copy-Item -Path $($file.FullName) -Destination $dstRoot
    }
}

LogWrite "`n------------------Estimate(s)-----------------"
foreach ($file in $EstimateList)
{
    LogWrite $file.FullName
    if ( $reply -match "[yY]" ) 
    { 
        Copy-Item -Path $($file.FullName) -Destination $dstRoot
    }
}

# If running in the console, wait for input before closing.
if ($Host.Name -eq "ConsoleHost")
{
    Write-Host "Press any key to continue..."
    $Host.UI.RawUI.ReadKey("NoEcho,IncludeKeyUp") > $null
}

Could someone help me understand what is wrong with running the script as a PS1 file?
