WordPress update to 5.6 crashed my site.

Greetings,

Auto update of wordpress to 5.6 has crashed my site. Below is the error I’m receiving:

Notice: register_rest_route was called incorrectly. The REST API route definition for wp/v2/user-generate-nonce is missing the required permission_callback argument. For REST API routes that are intended to be public, use __return_true as the permission callback. Please see Debugging in WordPress for more information.
