There are errors in defender code

I am seeing some errors in the Defender plugin code on my site. On the Security Tweaks page of Defender I see these 2 errors in Query Monitor:

1 GET https://cat*********.com/wp-includes/theme-compat/embed.php
500 Internal Server Error
Plugin: wp-defender

2 HEAD https://cat*********.com/wp-content/plugins/wp-defender/changelog.txt
