Hi Duy Khiem Do,

Please try resetting the Ansys folder by opening a file explorer and type %appdata% in the address bar.

Locate the Ansys folder and rename it to Ansys.old. Also, type %temp% in the address bar and rename the .ansys folder to .ansys.old

Try renaming .fluentconf and .cfx files (C:\Users\USERNAME\) to .fluentconf.old and .cfx.old.

Relaunch the application.
