Please check the Microflow and page access to that user role.
You are using a datasource microflow on the page. So when the page loads, it runs the microflow. However, your microflow has a Show Page action, so it tries to load the page, which runs the microfow, which shows the page, which runs the microflow, etc... You are essentially stuck constantly loading the same page.
To fix this, you need to remove the Show Page action in the microflow.
I hope this helps.
