I attempted to copy a feature in one layer and paste it into another layer, as I have often done. However, I got the message, "Crash dumped; minidump written to c:\Users..." The program then closed itself.
I uninstalled the program, restarted the computer, and reinstalled the latest version, 2.14.21.
Upon starting the program, I get the yellow exclamation mark message, "Plugin processing: The plugin will be disabled because it crashed QGIS during last startup...re-enable the plugin when the problem has been solved."
When I click on "Plugins" in the main menu, I get a list, and the explanation that ones showing in red have a problem. However, none of mine are red.
When I again try to copy and paste from one layer to another, I still have the problem—even using different layers.
Any idea what's going on, and what I might do about it? I am running Windows 10.
