Once you open a library in Calibre 5 it changes it in a way that is potentially incompatible with calibre versions prior to 4.23. So if you revert do not use an older version of calibre than that one.

Yes, that's what I mean. Just re-install the previous version.
Of course, you can also simply use the stand alone version of DeDRM.
In general, it's a good idea to do a full back up of your calibre folder before updating, especially if it's a major update like this is. I have the advantage that I have multiple macs, so I can run the older version on my laptop and then copy the dedrm'ed files to my desktop if I need to. But, I'll probably just hold off until they get things working again.
