Hi all , 4th time I got this problem (in a very short period) . Calibre suddenly doesn't open any ebook, inside and outside the library, (but it's not just a calibre viewer problem)
The first time was (probably) because I installed the 32 bit version instead of the 64 bit, the error message said a lot of things and mentioned this thing among the others (32 bit Calibre installed in a 64 bit Windows). Second time I don't know what happened, I reinstalled the same 64 bit version and all seemed to be right again. Third time was yesterday, I repaired the Calibre library from the dialog window (the calibre installer), today the problem showed up again, and I didn't do anything particular (neither the other times to be honest)

So, ebooks can't be opened, converted, from what I've seen news can't be downloaded. Like the other times, it appears a long—very long— error message ) ,(a particular line in this message says-
CriticalError: Failed to launch worker process )
Plus: in this error message there is every plugin name I have on Calibre, even the Python version name show up many times.

I got Windows 10 (on Acer laptop), And I don't know what could be the cause of this problem, some week ago my pc was with very short free space, I made some cleaning and now it's ok. It seems like the problems showed up after the Calibre 32 bit version was installed, I don't know if this is what caused such a mess on my Calibre. What could I do now to fix it once for all?
