One of the last actions in the log file is importing a file named "Canaro, Rafael - Private collection/Orquesta Rafael Canaro-Garúa-Jorge Cardoso.mp3". Try turning off auto-import and see if the crash problem goes away. If it does, try manually importing just that file and if there's a crash, let us know.
Also, I noticed your library is stored under your "Google Drive" folder, I wonder if there's a problem with that, since Media Center needs exclusive access to those files and the Google sync program may not allow that while syncing to the "cloud".
