This is likely a graphics issue, so resetting the 'appdata' will not help.
Is there any visualization node with good graphics card installed/setup on this cluster ? Here is the list of supported/tested graphics cards

If there is no node with good graphics, you can try software rendering mode but I can't guarantee that it will help
export LIBGL_ALWAYS_INDIRECT=1
export LIBGL_ALWAYS_SOFTWARE=1
export LD_LIBRARY_PATH=/ansys_inc/v201/Framework/bin/Linux64/Mesa
/ansys_inc/v201/Framework/bin/Linux64/runwb2 -oglmesa
If this still doesn't work, you will have to do pre/post processing on a laptop, ideally with graphics card, then just use the cluster for solving (but need to use batch command to submit the jobs)
