Hi @Eufranio,

The error seems to be coming from Imagify tools, which is an helper plugin for support purpose. If you disable the plugin, do you still have the issue?

By the way, we have an open pull request related to this: wp-media/imagify-tools#43

It indeed fixed the issue by disabling Imagify Tools. Thank you.
