Playground does not support components like lightning-record-edit-form or any other base components that requires a Salesforce connection.

You will need to use an IDE like vscode extension for Salesforce and Salesforce CLI to connect your local machine to actual Salesforce org to verify and play with components that require Salesforce UI API or Salesforce metadata API or Salesforce data.
