Recover large amount of files from Recycle Bin in OneDrive

Question

I have an account for OneDrive for Business through my university email. Slightly more than one month ago I deleted some files by mistake, and of course, I just noticed it.

I now found all the files in the OneDrive's Recycle Bin in the website, the problem is that they are 6000+ single files and I'd need all of them. If I try to select them all (struggling) it gives a timeout error.

So I'm forced to manually restore them by groups of 35-40 files at a time. I made a quick computation and it will take me more than 5 hours in this way.

Does it exist a faster and more automatic solution to the problem?

You can automate the restoration of files deleted that are in the OneDrive Recyble Bin with Poweshell.

The code algorithm would more or less:

foreach ($fileitem in $FilteredRecycleBinArray) 
    { 
    $filename = $fileItem.Title 
    $fileitem.Restore() 
    try { 
        $ctx.ExecuteQuery() 
        logwrite -Logstring "Item $filename restored successfully" -type info 
        } 
    catch  
        { 
        logwrite -Logstring "Item $filename failed to restore with error: '$_.Exception.Message'" -type error 
        } 
    }

Relevant related code:

$ctx = New-Object Microsoft.SharePoint.Client.ClientContext($OnedriveUrl)

And:

$Recyclebinarray=$ctx.Site.RecycleBin
$ctx.Load($Recyclebinarray)
try     {$ctx.ExecuteQuery()}
catch   {logwrite -Logstring "Failed Collecting all deleted Items from $OnedriveURL with error: '$_.Exception.Message'" -type error
        break}
