Comment (by siliconforks):

 I was able to reproduce this with the following steps:

 1. Install the Angell EYE Updater plugin by cloning the repository at
 https://github.com/angelleye/angelleye-updater

 2. Activate the plugin

 3. You might need `WP_DEBUG` set to `true` in your `wp-config.php` file

 4. Go to Dashboard → Updates.  (This should trigger a check for updates,
 which is necessary to reproduce the issue.)

 5. Go to Plugins → Add Plugin.

 If it doesn't work it may be because WordPress will not check for updates
 more often than once every minute.  Simply wait for at least 1 minute and
 then repeat steps 4 and 5 again.

 It looks like this issue is specific to the Angell EYE Updater plugin.  It
 adds a `pre_set_site_transient_update_plugins` filter to modify the
 `update_plugins` transient, and when it does this it creates an object
 which has only a `slug` property (and therefore it has no `plugin`
 property, so you end up getting the warning `Undefined property:
 stdClass::$plugin`):
