Please Help! CorelDraw crashes every time during saving.

Sounds serious.
Are you saving to a local disk or a networked one?

1. You can try to convert all of text to curves and export again.
2. If you use Color Styles, then you can try delete all of the color styles and export again.

I would try temporarily turning off the autosave, which should at least give you a bit more time to try to find what is causing this.

I've seen a couple of cases where people have unexpectedly generated gigabytes of content and a possible answer if you catch it soon enough is to select all objects on the page, copy to clipboard, keep the original file open and paste them into a new empty document -- which can sometimes be saved.
