Welcome to Atlassian Community. It's great to meet you!
This error could be caused by a single page in your space. You can try by doing a custom export and only export chunks of pages at a time until you reach the page that has an issue.
Otherwise, your log files are stored privately on our end. We can have a look for you if you raise a ticket on our support portal, support.atlassian.com.
Sometimes I've seen this issue if a particular attachment is corrupt or not readable, for example.
Another issue that could occur is if you have any pages that have a lot of macros on them. In that circumstance, I'm talking about users who have tens of Jira issues macros, for example. If you had pages like this you might experience performance issues when browsing to them.

Your best bet, to save you all that time and effort, is to contact the support team directly so we can have a look at your log file. It will tell us exactly the issue that your site is encountering.
Hope you are well.
