iTunes crashes when downloading is processing the file

I ran into something weird.  I switched users in iTunes and all of a sudden anything I downloaded crashes.  Ok no big deal, I'll log out and switch to the original user.  Nope now happening all the time for all users.  I searched and there are a ton of try this try that out there but nothing worked. 

What ended up working for me was deleting the whole iTunes folder.  When I relaunched it, it created all the folders and everything was working again.

OS: Mac OS 10.12.6
