Fehler beim Importieren - Einige Importvorgänge wurden nicht durchgeführt.

Hello,
here is the translation.

I have the following problem since today, until now I did not have the problem.

When importing images I get the following error message:
Some import operations were not performed.
Error trying to find a place for the imported file. (6)

Original German error text:

Einige Importvorgänge wurden nicht durchgeführt.

Fehler beim Versuch, einen Platz für die importierte Dateizu finden. (6)

Here is what I did:
6 files, all in TIF format (2021-08-008-8.tif, ...) I saved on my hard disk.
When importing, I have the following settings:
- Add (the images are already in the right location).
- Create smart previews
- Do not import possible duplicates
- Add metadata from my presets
Then I click on import.

After about 3 sec the error appears.
Some import operations were not performed.
Error trying to find a place for the imported file. (6)

Here is some more info about my system:
I am using Adobe Photoshop Lightroom Classic - V10.3 - Camera Raw 13.3.
My operating system, Windows 10 Home - V 2004 - operating system build 19041.1165.

Thanks for the help.
Regards Matthias
