What is the exact version of Lightroom that is installed?
I have this issue too.
I follow the instructions at Lightroom doesn't launch or closes automatically after splash screen, then it works for the rest of the day. The next day after, The same problem starts again.

If you are using Lightroom CC, and the develop module is disabled, then check to make sure that your creative cloud account is paid current. If it is, then sign out from the creative cloud application manager and sign back in and see if that resolves the problem.
