Capture the error from Remove-Item into the existing calculated property in PowerShell script to delete files?

How can I capture the files that cannot be deleted and their error message into a separate variable?

The below script can perform the deletion, but I'm not sure how to get the files that are still in use.

$totalSize = 0
$results = Get-ChildItem -Path $searchRoot -Filter *.log -Recurse | ForEach-Object {
	$_ | Select-Object -Property Name,
								   FullName,
								   @{ n = 'Size (MB)'; e = { [math]::Round($_.Length / 1MB) } },
								   LastWriteTime

	$totalSize += $_.Length
	
	$paramRemoveItem = @{
		Path    = $_.FullName
		Force   = $true
		Verbose = $true
	}
	
	Remove-Item @paramRemoveItem
}

$results
$totalSize

This is the error:

Remove-Item : Cannot remove item C:\ErrorFile.BAK: The process cannot access the file 'C:\ErrorFile.BAK' because it is being used by another process.
At line:17 char:2
+     Remove-Item @paramRemoveItem

Using error trapping and custom objects:

$totalSize = 0
$results = Get-ChildItem -Path $searchRoot -Filter *.log -Recurse | ForEach-Object {
    Try {
        # Remove '-WhatIf' to delete files
        Remove-Item -Path $_.FullName -Force -Verbose -ErrorAction Stop -WhatIf

        # You should try to avoid '+=' operations - please search Stack Overflow for rationale and alternate methods
        $totalSize += $_.Length

        # $Status populated with OK message
        $Status = 'OK'
    }
    Catch {
        # This block is only processed if there's an error in the `Try` block
        # $Status populated with the error message
        $Status = $_.Exception
    }
    Finally {
        # Output object for this item
        [pscustomobject]@{Name=$_.Name;FullName=$_.FullName;SizeMB=([math]::Round($_.Length / 1MB));LastWriteTime=$_.LastWriteTime;Status=$Status}
    }
}

$results
$totalSize
