A Microsoft file hosting and synchronization service.
Since restoring more than the first group of files is consistently failing, I would not continue trying different selection methods in the Recycle Bin. If you have an active Microsoft 365 subscription and these files were deleted within the last 30 days, OneDrive has a Restore your OneDrive feature that can roll the entire OneDrive back to a point before the deletion occurred. This can be much more practical when a very large number of files were deleted at roughly the same time. Microsoft documents this option here: https://support.microsoft.com/en-us/onedrive/restore-your-onedrive
Please be aware that this is not simply a “restore everything currently in the Recycle Bin” command. It undoes file and folder activity that occurred after the restore point you select, so changes made after that time can also be affected; files created afterward may be moved to the Recycle Bin.
