Did you determine what caused the OneDrive app to crash?
Consumer OneDrive was designed to sync your personal folders, namely:
C:\Users\your user name\OneDrive\Documents
C:\Users\your user name\OneDrive\Downloads
C:\Users\your user name\OneDrive\Music
C:\Users\your user name\OneDrive\Pictures
C:\Users\your user name\OneDrive\Videos
Is it possible that those folders have tens of thousands of changes? I wouldn't think so, but you know your personal folders better than anyone.
