The first guess is that the string 'URL' in the post is not the actual
string that "causes Latex to crash".  The next guess is that 'URL' is
actually a string with one of LaTeX's 10 special characters, with a
popular one being underscore (_) in this context.

The second argument to \href is simply a string that LaTeX can render,
so a URL is fine.

A URL can be used, but any special characters must be protected
somehow.  The \nolinkurl in the second argument provides such
protection, as does the \url solution mentioned above.
