KOreader "No reader engine" on PW1
The development builds after 2020.12 doesn't work for PW1. It restructures the cache, reload all cover thumbnails, then I get an error message "No reader engine for this file or invalid file" whichever book I want to open. The only solution is downgrade to the latest stable, however, no cover is shown after that.

Try with a nightly, there was a memory alignment issue in the zstd version used in the release, that was hotfixed a few hours later. It *would* unfortunately be fatal on a Kindle, given how the alignment trap is setup there

The problem first appeared with nightly 24, and it is the same even now with 30. I have a modern interface with no reader engine it seems.

PW1 is flat, so, more on that later, but 2020.12-27 worked out just fine on a K3, and -30 just fine on a PW2.

Well, I did find a fun Kindle special bug in the process, but everything's also fine on my end on a PW1 on 5.6.1.1 with -30.
I would have said try a clean install, but apparently you did, so, check the crash.log instead (in koreader/crash.log). |

I'm going to need the full context, not just an excerpt.

And this vaguely looks like an incomplete/badly updated install, so I'd try a *really* clean install, from scratch

Came back. Something changed in KOreader so when I run a book by kpvbooklet, I get this error message. And this was the very problem before too.
