Error #0 (0x851000000) - PTR only

Hiya - only effects shadows lands PTR - retail and classic are fine.

Error #0x851000000 Assertion Failure!

like I say, only effects shadowlands PTR - and yes, I have looked at the thread about this issue - tried all.

Ideas?

Sounds like an issue with the selected graphic api.

Maybe try the different Graphic APIs System > Advanced > Graphics API.
