There is all sorts of stuff in console. Not sure what to cut and paste in here. I backed up to 2.42, then 2.4.1, still the same behavior. I'm not sure what version I had, maybe 2.3 something. (I had upgraded calibre to 2.x about 2 weeks ago. I wasn't going to step back in .1 increments till I found one that worked. I went all the way back to 1.48, and it then worked fine. I was finally booting without freezing on startup.

I still don't see Marvin after installing Marvin XD and IOS reader apps with 1.48. I followed the instructions for customizing the IOS plugin. I get the error message ImportError: No module named PYQt5.

I do get the send to device button for my Kindle now with 1.48. I was not getting that with any version of 2.X calibre regardless of any options of configuration on startup wizard with IOS and Marvin plugin not installed.

I'm guessing there is something wrong with the IOS reader app plugin? For now I can send to Kindle and manually drop books into my iphone 6s plus into Marvin from itunes.
