Not able to Create Folder or Dashboard

I have recently upgraded to Grafana v8.4 in AWS Linux EC2 instance.
Also I am trying to create a folder or Dasboard using Admin user.

I am trying to create a folder to sort the dashboards into the folders. But I am not able to create any folders. Below is the screenshot of what appears when I click on Create New Folder.
I do not see any text box to enter the name and save it or configure the settings of the folder.

Also, I am not able to see the preferences details for any user.
Could this be due to some issue in the installation.

When I am selecting create new dashboard and trying to save it, I am not getting any text box to enter the name and save the dashboard.

Is there any specific configuration that needs to be done to be able to create the folders.

Thanks and Regards,
