Unable to rename file

mv: cannot stat ‘/app/assets/ccfc9e2e-e1fa-4dd0-838d-c3b5bb122b10%2Fahh.mp3?v=1590476888665.1’: No such file or directory

i have done wget (link url) then tried to rename. closed the editor and console 2-3 times and started again but no use

I would recommend renaming it inside of the editor. You just click the three dots near the file and click rename.
