Good Morning
 
It is not possible to say why this happens and help from that error message alone – if this model is of importance to your work and if you are using a commercial and supported Ansys licence, please create a support request (Ansys customer portal) and we will try and help to troubleshoot and if possible try to recover the project model that might  have been corrupted (thus causing this error).
 
Thank you
 
Erik
