After updating to the most recent version (7.5.1 currently) I now have the issue where using the Calibre ebook viewer crashes when loading any ebook. I ran it with the debug flag and got the following output:

Code:

QPA platform: windows
devicePixelRatio: 1.0
logicalDpi: 96.0 x 96.0
physicalDpi: 81.55183946488295 x 81.64285714285714
ApplicationPaletteChange event ignored
Using calibre Qt style: True
ApplicationPaletteChange event received
QWindowsGLContext::makeCurrent: wglMakeCurrent() failed (The handle is invalid.)
QRhiGles2: Failed to make context current. Expect bad things to happen.
Failed to create QRhi for QBackingStoreRhiSupport
Failed to make context current.
Failed to make context current.
Failed to make context current.
[0.000] Load of book started
[0.016] prepared emitted
[0.047] webview loading requested

I've had this issue after updating in the past, but restarting always seemed to fix it. However this time that doesn't seem to be a solution. Has anyone encountered this? Perhaps a library I need to reinstall? Downgrade a graphics driver?

Thanks!
