Powershell Group-Object Fails when passing curly brackets "{" or "}" Is there a way around this?

(EDIT: Just found this: https://github.com/PowerShell/PowerShell/issues/20711)

Here's sample log files being used for input:

Checksumlog1:

Here's the code:

$checksumlog1Content = Get-Content "checksumlog1.log" -Encoding UTF8 | Select -skip 1
$checksumlog2Content = Get-Content "checksumlog2.log" -Encoding UTF8 | Select -skip 1

$checksumlog1Objects = $checksumlog1Content | ForEach-Object {
    $checksum = ($_ -Split ' ',2)[0]
    $file = ((($_ -Split ' ',2)[1]) -split ' ' | select -skiplast 2) -join ' '
    $sizedate = ($_ -Split ' ' | select -last 2) -join ' '
    [PSCustomObject]@{
        'Hash' = $checksum
        'File' = $file
        'SizeDate' = $sizedate
    }
}

$checksumlog2Objects = $checksumlog2Content | ForEach-Object {
    $checksum = ($_ -Split ' ',2)[0]
    $file = ((($_ -Split ' ',2)[1]) -split ' ' | select -skiplast 2) -join ' '
    $sizedate = ($_ -Split ' ' | select -last 2) -join ' '
    [PSCustomObject]@{
        'Hash' = $checksum
        'File' = $file
        'SizeDate' = $sizedate
    }
}

$CompareLog1Log2Obj = Compare-Object $checksumlog1Objects $checksumlog2Objects -Property Hash,File,SizeDate -PassThru -IncludeEqual| ForEach-Object { $_ }

$nonMatchLog1Obj = $CompareLog1Log2Obj | Where-Object SideIndicator -eq '<='
$nonMatchLog2Obj = $CompareLog1Log2Obj | Where-Object SideIndicator -eq '=>'

$groupDiff = Compare-Object $nonMatchLog1Obj $nonMatchLog2Obj -IncludeEqual -Property Hash,File -PassThru | Group-Object File | Where-Object Count -ge 2

ForEach ($item in $groupdiff.Group) {
    "$($item.Hash) $($item.File) $($item.SizeDate) $($item.SideIndicator)"
}

If the filename contains a curly bracket "{" or "}" (like I added in "checksumlog2.log" it throws an error:

Input string was not in a correct format. Failure to parse near offset 12. Expected an ASCII digit.

Is there a (hopefully simple) way to get this to accept those curly brackets? Thanks.

This appears to be an issue with current release PowerShell version 7.4.0. It is fixed with latest Release Candidate 7.4.0.101: https://github.com/PowerShell/PowerShell/issues/20711
