Unable to repair "Unknown download error"

Hello everyone. Thank you for being with you. And Happy New Year to all.

I created a ticket yesterday for a problem that I've been trying to solve alone for 1 week already and I'm probably going crazy.

The ticket service has not found the solution and is no longer responding.

I have Native access 3.8. I tried to delete, and reinstall, I also deleted all files linked with native access, I removed the private relay, I tried to send the download to another location. Whatever I do. By following the advice on the forums or native instrument service, nothing works.

No download works. "The download failed".

I need your help now. Thank you very much in advance.
