Export is an empty file

When I first installed Flamingo it worked great and I was able to export to a csv with all the info intact (a couple months ago)…I’m now up to almost 30,000 entries and when I try to export I get nothing but a blank csv file…is it the number of entries that is causing a problem? The info is all there in my database…just can’t seem to export it. Nothing else has changed…same install, no new plugins…
