After reviewing the issue on our local environment, we’ve identified that the problem is caused by the wp-graphql-woocommerce plugin, specifically version 0.21.2.

When testing with an earlier version of the plugin (0.21.0), the issue does not occur.

As an immediate workaround, we recommend downgrading the plugin to version 0.21.0. We are still checking this further.
