modified AnythingLLM\resources\backend\node_modules\epub2\lib\epub.js

at this line
title = (branch[i].navLabel && branch[i].navLabel.text || branch[i].navLabel || "").trim();
like this
title = (String((branch[i].navLabel && branch[i].navLabel.text) || branch[i].navLabel || "")).trim();
restarted and it works

Are there known steps to reproduce?

Try different epubs from public free re source a many will fail
