Do you have any external drive connected to your computer? If, yes please disconnect it and then try using Lightroom.
May I also know whether you are working on a Mac or Windows system?
have yes all my raw files are on an internal Caddy drive, but I do have external drives connected to my windows PC.
Please disconnect the drives and then give a try.
When exactly does LR 6 crash, and are you using a Wacom ?
yes I do have a Wacom,
it seems to crash when you start to work fast, if you keep it at a very slow speed it's fine.
I never had problems with lightroom 5
