One of LMS' database files got corrupted in the crash. You'll have to
shut down LMS, wipe cache.db* and library.db*, then restart LMS. If that
didn't help, you might have to remove persist.db*. Take a backup of the
files before removing them. This way you could restore them in case you
removed the wrong files.
