If you’re getting far along on opening the project and then it hangs, it may have it a bad piece of media.
Hopefully your media is in one place…if so…rename that folder slightly….
then try to open the project….
this should force it to open but ask you where the media is…
Offline all media and make sure the project opens.
Save AS the project
then start relinking the media in small batches….saving after each small successful batch…
eventually you will find the culprit that will make you crash….
re open last saved version, skip the file that cause the problems and relink the rest of the media…
hope that helps….
