Unable to Save download. death1.ogg

While I was trying to play snapshot 17w14a, I got this report: Unable to save download. death1.ogg
Name: death1.ogg
URL: http://resources.download.minecraft.net/13/135ac58e0aeeb460cc850d7b435562bf0849ca2e
Error details: Attempting to move successful download to C:/Users\Ana\AppData\Roaming\.minecraft\assets\objects\13/135ac58e0aeeb460cc850d7b435562bf0849ca2e
The process cannot access the file because it is being used by another process
Filename on disk: ea0c-913a-aa9a-ab7d
Path: C:\Users\Ana\AppData\Local\Temp\ea0c-913a-aa9a-ab7d

So What can I do to solve this? I really want to play the newest snapshot but I can't.
