Hi Abinav,

The file format (.hfss) is a very old format used for saving the HFSS project designs before the introduction of Ansys Electronics Desktop. As shared by my colleague, recently there is a change in the geometry kernel. So, the hfss projects cannot be opened in AEDT versions 23R1 and beyond.

Since you are using the student version which is 23R2, it is not possible to open the project. It is not possible to use the older versions of the AEDT student version. So, I recommend you to contact the sender of the model to convert it into the AEDT format which can be opened in the current student version. Please note that it is possible to access the AEDT version of 22R2 and below are still accessible for commercial and academic licenses. 

Best regards,
Praneeth.
