Hi phillipk ,
This is a indeed a GPU related issue. Please update your GPU drivers from the manufacturers website.
In the mean while, disabling "Use Graphics Processor" (Preferences > Performance), should help load the Develop module.

OK I unchecked graphics processor as other posts suggested, but why does this work? does it reduce performance?
I did check driver and it said it is up to date. Does disabling Graphics process reduce performance?
Actually, for many people, disabling the GPU increases performance. In any case, it's a moot point--LR on your machine needs to have the GPU disabled or it won't run properly.
