I recently updated to Calibre 4.19 on my Windows 8 laptop, after using an old version for over a year. Now the problem is whenever I try to open the ebook viewer inside Calibre, it appears for a second and then closes automatically. Not just while opening books, even if I simply launch the ebook viewer directly from start menu, the same thing happens.

I tried running Calibre in debug mode but it seems to have entries about Calibre management app only, not the viewer. I updated to 4.20 as well just now but same issue. Any idea how to fix this?
