System.Drawing.Bitmap($_.FullName) fails with "Online only" files stored on OneDrive

Question

Hi,
I want to retrieve the DateTaken from JPG files that are stored on my OneDrive. If the file is available offline, the code works fine. However, if the file is "Online only" the code below breaks when creating the New-Object System.Drawing.Bitmap
and generates the following error: "New-Object : Exception calling ".ctor" with "1" argument(s): "Parameter is not valid."
Is there any way to work around this problem?
[reflection.assembly]::loadwithpartialname("System.Drawing") | out-null
Get-ChildItem ($Path + "\*") -include @('*.jpg', '*.jpeg') -Force | ForEach-Object {
        if (! $DateTimeArg)
            $pic = New-Object System.Drawing.Bitmap($_.FullName)
            $ExifDate = $pic.GetPropertyItem(36867)
            $DateTaken = (New-Object System.Text.UTF8Encoding).GetString($ExifDate.Value)
            $DateTime=[datetime]::ParseExact($DateTaken,"yyyy:MM:dd HH:mm:ss`0",$Null)
            $pic.Dispose()

Right, if the file is available offline, it means the JPG file is stored in your local computer, and consequently, the variable $Path is meaningful, because it refers to a folder in your local computer.

Right, if the file is available online only, it means the JPG file is
not stored in your local computer, and consequently, the variable $Path is meaningless, because it refers to a folder in your local computer (it doesn't matter which) that
does not contain the image.

Yes. right click on the JPG name (on file explorer) and make it available offline.
