Plugin Breaks Login

After installing WooCommerce Betaout, I get the following output on a blank page after attempting to login to WordPress through either the WooCommerce login, or wp-admin. As soon as I disable the Betaout plugin, I can login normally. If I clear all browser cookies, I can login normally for a time, but after a while this issue comes right back. However, sometimes clearing the cookies doesn’t help. It isn’t immediately clear how to bypass this issue without disabling the plugin.
