When you go to file open can you pick the option box you will see a lot of options to Keep Windows, cameras, etc. turn all of these off and see if the data loads.
Once loaded you might need to create a new perspective camera to vie the data.
If that works then you can try opening it again with some of the more important elements like Layers. See if it opens and try to recover as much of your file.
Hope that helps.

If what Robin suggested does not work, you can try to loading the file into an older version of Alias, if you have access to one. If that works there still may be some data loss.
An alternative to different version is to open it in maya, it sounds like something is getting in a loop that can not be broken. If you don't have maya share the file with me and I will see if I can open it and send it back.

Unfortunately The best we could is recover his file in 2017 ( a version before subdivs) so his subdivs were converted to nurbs. It can be read by 2020 (the first release of subdivs), but any file written out cannot be read by a later release.
