Hello AnthonyGonz_,
If you're unable to download files in Safari, you can start with these recommended steps: If you can’t download an item from the web using Safari on Mac
If you have any sort of security/antivirus/vpn software installed on the computer, try disabling it as that may be preventing downloads.
Also, make sure you've covered the basics like restarting the computer and making sure it's up to date.
Shut down or restart your Mac
Update macOS on Mac
If Safari downloads are still not working, you'll want to isolate if it's a user account based problem or a system wide problem. You'll want to create a test user account on the computer, then switch over to that account and try downloading something in Safari there to see if it works or not.
Add a user or group on Mac
Cheers!
