The **atio6axx** 'Problematic frame' in **hs_err_pid38960.log** is part of the **AMD** driver for the GPU.
There is a bad version of the AMD drivers that instantly crashes on an OpenGL task.
Try fresh reinstalling your drivers from [https://www.amd.com/en/support](https://www.amd.com/en/support)
**If** you don't have an **AMD GPU**, then you need to tell your system to use that GPU
instead of the integrated GPU of the AMD CPU, steps below.
