Hello - I'm having some issues with getting vellum to do anything on a newly refomatted PC

I keep getting a crash following this error:

1 error generated.
OpenCL Exception: <kernel>:1907:20: error: blocks support disabled - compile with -fblocks or for OpenCL 2.0

The PC is running win10 - Nvidea 2060Super and tried latest Studio and Game drivers.
Am running 19.5.403
Any thoughts?

Just downgraded to an older Studio version of the Nvidia driver and seems to have fixed things.
Appologies no doubt this has been mentioned somewhere before

This was fixed in 19.5.408, 19.0.775, and 18.5.1098.

I am also facing this issue in Houdini 19.5.403



Is there any way to solve it without updating Houdini to a daily build or downgrading the Nvidia studio driver?
