Hello @tjpolanski,
My name is Henry Eduardo and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
I am sorry about the issues you are having exporting your vault. Can you please try to export it using the browser extension instead?
Please let me know if this worked or if further assistance is required.
Thank you,
Henry Eduardo | Customer Care
Thanks Henry, tried your suggestion and it worked, saved me a lot of work.
