Hmmm, that could be a false alarm, some plugins give these errors by mistake. Unless some custom code or something was added inside the theme or to your site admin. You can always upgrade to the newer version to see if that fixes the issue if you want. The version you’re using is from a few years ago.
You can also try and disable any other plugins you’re using to see if there may be some type of conflict.
I seriously doubt it’s anything to worry about just based on how these Child themes are built, but if you want to upgrade to the newer better version you have that option. The new version is a Full Site Editor (FSE) based theme built with Gutenberg/Blocks and doesn’t require the Genesis Framework – https://appfinite.com/shop/oasis
