Thanks! It looks like there's a fix in 407 and then a second fix in 408 as well.

What GPU driver are you using? I started getting a ton of OpenCL errors on 19.5.368 when I updated to the latest Nvidia Game Ready driver (522.25) (just doing simple cloth sims). I rolled back to 517.48 and everything is working again. There are reports about that driver causing problems with other 3D software as well. They must have done something with their OpenCL implementation. Not sure if the same problem is on the Studio driver or not.
