Hi Pouyan,
I appreciate your patience. 
For clearing %appdata% you can follow the attached link
https://featips.com/2022/02/11/when-all-else-fails-reset-appdata/#:~:text=Here%20is%20how%20you%20can%20reset%20ANSYS%20Appdata%3A,v211_Old%207%20Launch%20ANSYS%20and%20refresh%20the%20project
for %temp%- follow the same method and rename the .ansys to .ansys_old

For the other queries, I think it might be an issue while extracting results up to a large extent of 30,000 timestamps. Do you use the Ansys student version ( Free version)? Are you facing this issue with other system or other Ansys version too? Have you checked the graphics card updated or not? Please let me know. 

Regards,
Sampat
