For any who are interested, I ran configure.py. It turned out that LyX was failing because of a .layout file I no longer use. When I copied my favorites into the new copy of LyX, I must have not been thinking and copied this old one in as well.
I'm not sure why it didn't work (it used to), but removing it solved the problem.
