html 2 epub will not convert

[Amalthia]

I'm not sure why Calibre won't convert my html files to epub. I did copy the error message. I tried single convert, bulk convert, turning off the program and restarting it. I'm currently using version 6.55.

I haven't changed any settings on my computer since I last converted to epub a few days ago. The only thing I changed was upgrading to the newest version of Calibre. Please let me know if I need to leave a ticket. Or if you see something that I'm missing. I'd appreciate any and all help.

It's a bug, will be fixed in next release. Turn on the default cover for epub or specify your own cover in the meantime.

Will do, thanks!
