Is there some trickling database in the background?
The behaviour vaguely described sounds like a problem that was seen with 4.8.10956. It was heavily discussed in the thread for that firmware, and was so such a problem that Kobo actually stopped sending that firmware out. It mainly affected sideloaded books, and they could frequently be opened the a second time. There was also a relatively simple workaround that reduced the significantly reduced the frequency of the problem. This problem was fixed with firmware 4.8.11073.

Now problems I have with your report:

Under no circumstances would I use the word "crash" for this. There were no error messages, you could continue doing things, the device didn't restart. Not a crash.

What is an "Overdrive book"? Is it a book you borrowed through the Kobo store? Or did you download it via ADE and sideload it from there? If the latter, then DRM made the problem I mentioned above worse.

"new fw" doesn't mean anything. The way Kobo offers firmware means that it can be a month to reach everyone. Plus, you posted this a few days after firmware version 4.9.11311 was released. Right now, depending on the device, where you are in the world, were you bought the device, where you signed up to your Kobo account, the "new" firmware could be one of four or five different versions. And if I include the Mini, there are two more. With all that, it is very likely that your two devices are running different firmware versions. Taking the 30 seconds to check and be explicit about it in your post cost nothing and saves a lot of potential misunderstanding.


Now, as stated, this sounds like a problem with firmware version 4.8.10956. It affected sideloaded epubs if the "Publisher default" font was being used. Changing to another font, other than the two Kobo fonts near the bottom of the list, would largely avoid it. Kobo have fixed this with 4.8.11073 by changing the default font back to Georgia.

There are some other causes for something like what you describe, but they usually means a book with errors, or reopening a book after it was replaced on the device.
