Deactivation Notice in WP 5.3.2

Hi Scott,
When I updated to version 1.6.0 using WP 5.3.2 I ended up with this message: wp-updates-notifier/wp-updates-notifier.php has been deactivated due to an error: Plugin file does not exist.
But when I logged out and back in I activated the plugin and it stayed active. I logged out then in again and it was still active. Just thought you’d like to know that this happened when I updated it on 6 websites that I use this plugin on.
It’s a great olugin. Thanks for keeping it alive. I use it on all of my websites. I would be very bummed if it didn’t work anymore. Thanks again.
