Calibre 5.0.1 Unhandled Exception

I've just updated Calibre to version 5.0.1 and find that the program won't run. Instead I get an error window titled: Unhandled exception running calibre.
The error message says:
---------------------------
Unhandled exception running calibre

Working here, More Details

It's working here on both my upgrade and fresh install on Windows 10 x64 build 1903. Please "include system details (OS version, 32 vs 64-bit, install path, new vs upgrade, etc)" as well as any additional relevant details (antivirus, antimalware, whether a local copy works, etc) and anything else you think my be interfering with the app on your PC. Also try it on another PC as a test if you have access to one.

Sometimes, the impossible can become possible, if you're awesome!

Try This

First make a backup. Then delete your calibrePortable\App\calibre dirtectory. Then install a fresh download right over it (being sure it's installing to X:\whatever\calibrePortable).

Additional Working

calibre Portable 5.0.1 also installs, starts the wizard (selecting generic) and comes up with the library view on first run on Windows 10 x86 Build 2004, Windows 10 x64 Build 2004, Windows 7 x86 (all updates), and Windows 7 x64 (all updates). I can not reproduce your issue on any PC or virtual machine I have access to. Everything works as expected.

I need to determine what is interfering with calibre on your machines to troubleshoot further. The more details that could lead to that the better.

Also, if you are able, please install the local version and see if that works as expected. And try installing their official slightly less portable version to see if that works.

5.0.1 Rev 2

I've pushed out a rev 2 that does a full clean upgrade of App for existing users. Anyone still having issues likely has an incompatible plugin or profile setting going on due to the 5.x series release.

Publisher Question

That would be a question you'd need to address with the publisher of the app. We just make it portable.
