Phone "cannot be identified" message

Anmeldedatum: 24.11.2020 Beiträge: 1

I had to reinstall the OS on my Samsung Galaxy J7 Prime phone and since I cannot connect anymore. I tried everything (I think) said in the phone and the Windows 7 configuration. On all modes (WiFi, BlueTooth or USB) the phone is found, but I get the same message: The phone cannot be identified.
Here is the log file:
