    Can you confirm a few things about the Events main form that’s failing to open in the classic form editor?


    • Does the form have any subgrids? If yes, are any using the Power Apps grid control (modern grid)?

    • Are there any PCF (custom) controls on fields?

    • Is there an embedded Canvas App, Web Resource (HTML/JS), or an iFrame on the form?

    Those components are common triggers for the classic designer to throw a generic “An error has occurred”, while the same form still opens fine in the modern designer.
