Logic Pro crashes when installing Sound Library helper tool

When Logic Pro is open, after a few minutes I get this pop up window telling me that Logic needs to install a helper tool for the sound library. Whether I click cancel or enter a password, Logic crashes. When I go to reopen it, the same window pops up. After a while, Logic does the same thing. Whether I'm recording, building or editing a track, the same problem occurs. Is there a solution for this?
