Safari Browser will not download files.

The download icon pops up quickly on Safari address bar, then disappears, ~0.5 sec.

File cannot be found anywhere.

Have tried:

"Safari"/ "Settings"/ "General"/ "File download location:"/ ( using different Folders ),

"Safari"/ "History"/ "Clear History"/ ( deleting browser history),

"Safari"/ "Settings"/ "Privacy"/ "Website data"/ (deleting data),

How to download in "Terminal" App ? Will that work ?

System:

macOS Sonoma 14.4.1,

MacBook Pro,
