Ebook Viewer Issue (W11)

[Breezy]

Hi all,

I just reinstalled Windows after switching out an intel processor and mobo for an AMD processor and mobo. In the previous install, I had used Calibre with no issues. However after the fresh install, Calibre now refuses to open up ebooks for view from the main library.

I have tried using calibre-debug -w in cmd, and that is able to open up ebooks with no issue. I'm confused as to why Calibre Library gets stuck on "Loading book..." when calibre-debug does so perfectly fine. I've tried with both 7.15 and 7.23 and both display the same issue.

Any help is appreciated, thanks.

Ah, for reference, this was the debug output:

Try a reboot in safe mode and see if it works there first.

I rebooted into safe mode, and am able to open ebooks from the Calibre Library without issue. What could be the cause of this? I have the latest Nvidia drivers for my GPU from the Geforce Experience app, so I don't think it would be related to that (as I saw from other forums drivers were mentioned)

Okay nevermind, apparently rebooting into safe mode, opening an ebook, then relaunching windows regularly somehow fixed the issue, and I can open ebooks without issue now. Thank you kovidgoyal!

I'm stuck with the same issue, also using a Nvidia GeForce graphics card: GeForce 9600M GT on Windows 10.

I have tried rebooting in safe mode, but that didn't help. I have also tried disabling the GPU with:

QTWEBENGINE_CHROMIUM_FLAGS="--disable-gpu"

For the moment, this, too has not worked.

I would appreciate any help you can offer.

Best wishes,
