Can you kindly check

Thanks for the amazing tool though. Beats most of the modeling suite out there

How do I solve the issue ?

There will be a fix in tomorrow's build from https://builder.blender.org/download/.

This latest error should be solved by rB10fa3b790fb8: Fix T60450: Cycles broken GPU denoising after recent changes..

By the way, I guess you have either a quite old or very new graphics driver, because I don't get those OpenCL errors. So I'm flying blind a bit fixing these things.

Hmm That's very strange. I'm running on AMD R7 265. I tested both on 18.9.3(Nov 2018) and 19.1.1(Jan 2019) driver. both are facing same issue

Karthik Hebbar (deltamish) added a comment.Jan 18 2019, 5:39 AM

Hey Downloaded the latest version of blender 17 Jan version. the Open CL issue is gone. But when I put on GPU compute bake with tile size 128X 128. My entire PC froze up and I had to turn it off manually
