OPF mode not working

[Roshri]

When trying to write metadata to an epub in opf mode, komf throws an exception and doesn't write anything to it. At first I thought it was related to switching my library type from Book to Light Novel in Kavita, but it's also happening on other libraries I haven't changed yet.

I don't know which one of these solved the issue

• Tried running komf from a new terminal
• Added Calibre's install directory to path
