How to solve this problem?

This seems to be an EasyPrint issue. Please check Weasy print document.

I had a similar issue (with lib gobject.so.2) and it was because weasyprint requires a GTK3 runtime which needs to be installed on Windows: https://github.com/tschoonj/GTK-for-Windows-Runtime-Environment-Installer

After installing, it worked fine and it might be the same reason here.
