Robocopy bug in Windows21H1

I use Robocopy since many years for backup and disk synchronization.
Now I've updated my computer from Windows 10 1909 to Windows 10 21H1 and my scripts failed.

As soon as I use the option /EFSRAW no file is copied.

Under Windows 10 1909
Robocopy /MIR source dest /EFSRAW
Works fine

Under Windows 10 21H1
Robocopy /MIR source dest /EFSRAW
Creates only the folder and copy no files.

Without /EFSRAW it copies the file correctly

I think this is a bug in robocopy
Has everyone a fix for this?
