Ebook Viewer going nonresponsive on startup
Every time I try to open an ebook no matter what format it's in in calibre. The ebook viewr comes up and is completely white and immediately goes nonresponsive and I have to end task in the task manager to close it.
Yet when I run calibre-debug -w it pulls the e-book viewer right up, and I can select any ebook of any format that I have and am able to read it |

You will most likely have assigned ebook-viewer.exe to a specific gpu, that is known to cause this.

If you are running Calibre on a laptop that has dual-GPU, configure Calibre and/or ebook-viewer.exe to use the other GPU. That has solved some problems with Calibre.

The ebook viewer is not assigned to any specific GPU. I only have one GPU in the desktop. If I run the portable version of Calibre the viewer comes up just fine. It only seems to be the installed version that has the issue with the viewer for some reason.

The portable and installed versions use the exact same code. *Something* on your machine is interfering with the installed version. The usual suspects are GPU drivers, Antivirus/security software, other random malware.
