Calibre error connection to Kobo Libra 2

Hello!

I have a very annoying issue with the sending of books to my Libra 2 (4.38.23552) via Calibre 8.16.1:

I am sending books by batches of 500 to 1500, and from the Calibre standpoint everything checks OK...and the after disconnecting the reader, the "content importation" stops at various percentages, and many of the transferred books do not appear on the Libra 2 (they are physically present)...

I go back to Calibre after reconnecting, and Calibre now shows only the books whose content has been imported, so everything happens like the "not appearing" transferring books are not there anymore...except they are however physically present!!!
I then try to gather all these books and transfer them again, and I get some more but usually not all of them...It is extremely frustrating, and soooo Kobo!
And now, during my last transfer operation, I got this error 22 invalid argument! Argh!

Here is the traceback:

calibre, version 8.16.1
ERREUR : Erreur: Erreur pendant la communication avec le périphérique

[Errno 22] Invalid argument

Traceback (most recent call last):
File "calibre\devices\usbms\cli.py", line 55, in put_file
File "shutil.py", line 200, in copyfileobj
OSError: [Errno 22] Invalid argument

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "calibre\gui2\device.py", line 110, in run
File "calibre\gui2\device.py", line 661, in _upload_books
File "calibre\devices\kobo\driver.py", line 2311, in upload_books
File "calibre\devices\usbms\driver.py", line 327, in upload_books
File "calibre\devices\usbms\cli.py", line 61, in put_file
OSError: [Errno 22] Invalid argument

What happens?

And I have a request for M. Goyal: would it be possible to not stop the book transfer when a book related error appears? It is not a big issue if you transfer 10 books, but at 1000 it becomes frustrating...

Funnily enough, I have zero issues with Pocketbook/Vivlio (and my library is very large).

Thanks a lot for reading me!
