I am facing the same error : ! LaTeX Error: File `l3backend-pdfmode.def' not found. I have seen some comments mentioning to go to the "Update DB" option in the miktex console. But I am not able to find it. Can anyone help me with a screenshot of how to find this option ? Would be really helpful.

The "Update DataBase" option is a little bit hidden in MiKTeX Console.
