Upgraded from 3.6 to 4.4 Unhandled Exception for a plugin during running the app in visual studio

Received this error after upgrading from 3.6 to 4.4. In Visual Studio when I run the project in the 4.4 version I receive the below error in VS can someone help me with resolving this issue? I am unable to load the admin site locally to remove and add the plugin. I had rebuilt the project several times and still saw the issue.

Edit App_Data\plugins.json and remove the AnywhereSliders plugin from the list.
Hopefully the website will run then and Admin will be accessible
Later make sure you have the latest version of the plugin
Then try and re-install the plugin

Thank you so much. I had the same issue with every plugin, after i removed all the plugins from the json file i was able to see the start up screen on 4.4.
