Hi, check whether your graphics card is compatible. Adobe Photoshop Lightroom Help | Lightroom Graphics Processor Acceleration (GPU) Troubleshooting & FAQ
I have been having huge problems with LR freezing when changing between modules. I initially thought it was the UAC in Win 10 that was causing the problem and running as an administrator worked for a little while, but it is freezing again. I had no problems with Win 7. My graphics card isn't listed as being incompatible but I am going through the trouble shooter now.
Back again, in that trouble-shooter there is a section to manually disable the graphics processor. Give that a go. It worked for me and I no longer hand LR freezing.
Problem appears to be resolved after disabling graphics processor. Thanks
Glad you got it sorted. Hopefully the bug will get fixed in due course.
