This is a well know issue look at: https://setiathome.berkeley.edu/forum_thread.php?id=84694

Revert the Nvidia to the 431.60 and all will be OK

Mentioned in multiple other threads- your video driver is the problem.
Driver version: 441.66

Only drivers 431.60 or earlier can be used without causing issues on some Arecibo WUs.
