After installing the v5.6.0 update the app UI briefly displays, showing all notebooks, but then changes to a completely blank window.
Tried launching the app with logging enabled and get the following (see attached screenshot).
Just install the app and launch it
Hi Brian,
Thanks for the report.
I guess one of the installed plugins is causing the crash.
Can you tell me which plugins you’ve installed?
Can you please try manually uninstalling them?
They are installed here:
%APPDATA%\inkdrop\packages\Hello Takuya,
I tried uninstalling the plugins one by one. It appears to be the web-clipper plugin that caused the problem. Restored all the other plugins with the exception of the web-clipper and it is working now. Thank you.
In the packages folder I now have the following plugins:
Yeah that makes sense because web-clipper is already deprecated a long time ago.
It should have been ignored in the app as well.
But that proves that you are a long-time user 
Great to know that it’s been solved! Have a nice day.
Thanks for the info. I had the same issue. I can confirm it was the web-clipper causing the issue.
