After I posted my original message, I noticed that all my collections were now empty. Also some other big epubs I tried to open also resulted in reboot. I was able to open a huge one that had previously been opened but I think it was the ones that I'd never opened before that were causing reboots.

In any case, I ended up doing a factory reset. It's a pain in the proverbial, because I had to then re-update the firmware and then patch it (there's some of the patch options that I can't live without). And now I'm in the process of re-loading all my ebooks (around 1500) on the reader and it's a slow process since they're being converted to kepub on the fly.

Obviously, the factory reset fixed the problem.

I wonder what caused the problem. I can imagine that it could be this issue of a catalogue generated by Calibre. In any case, it must have been something to do with the transfer of ebooks from Calibre to the ereader. Maybe something to do with the Kobo extended driver plugin. I just hope it doesn't happen again.

I just found a thread a few pages back about a similar problem to mine - large book no longer opening and causing reboot (large in that case was less than 20 mb). In that case they did a factory reset like me and it also fixed the problem. In that case, they didn't update the firmware after the reset. In mine, I updated it even before trying to sideload any books on the device, and it worked anyway.

The good thing about all this is that I was on firmware 4.3.8871 before the reset, and now I found out there was a later version 4.3.8966 which I installed (I'm aware there an even later version released in the last few days, but as it's not yet patched I didn't installed it). With this new 4.3.8966 version, the reader appears to be more responsive. The dictionaries for instance open definitely faster (however when I tested it, I had only a few books on the device - maybe once the 1500 books are on it, it might be different).

In any case, thanks for replying to my message. It always nice to know you're not the only one having a specific problem. By the way, in my case the book would not open if I tried immediately after the restart.

Cheers
