.hm files are not opening (Hypermesh)

Hi,

I am not able to Open saved .hm files. When I open saved .hm file in fresh session, the the session gets closes automatically/immidiatly.

I am using Hypermesh 2023.1 since 2 months and saving .hm files daily. No issue till yesterday, but when i tried to open ,hm files today facing with issue (no error message, session closes immidiatly)

Even, I tried others engineers .hm files and issue is the same.

Surprisingly, geometric models are opening(CAD) but no .hm model is opening.

I have 50 GB free space in C drive. 

Please give me pointer/solution.

Regards

Vishal A
