Always getting Unknown error
All versions after 2.6.4 crash.
Help please.
There is no other information available? Like does VEAI start, what are you doing when this error occurs, OS, RAM GPU etc., etc.
Please raise a support request at the main website.

Same, constantly. Arc A770 crashes with an unknown error after like 10 minutes of video. I am stuck on version 3.1.7 until they fix this bug. Rendering is about 20% slower in this version than 3.1.10. 
Support was contacted, they are “waiting for development to go through the logs.”

I keep getting this error with an arc A380 as well. My rtx 2080 works fine.
I have an RTX 3070 but it still crashes with the UNKNOWN ERROR message. : (
A770 - same thing. It works fine on certain workloads, and others I get the unknown error. This has been going on for like a month.
It’s a driver related problem, you can read Intel’s beta driver version notes;

"Topaz Video AI may experience errors when using some models for video enhancement."*
