It looks like your properties are in random order and missing the BEGIN:VEVENT/END:VEVENT.
iCalendar is following a fixed structure with components as containers for properties (and potentially other components). See https://www.rfc-editor.org/rfc/rfc5545#section-3.6
So you should have something like:
BEGIN:VCALENDAR
... VCALENDAR properties go here
BEGIN:VTIMEZONE
... VTIMEZONE properties go here
BEGIN:STANDARD
... STANDARD properties go here
END:STANDARD
BEGIN:DAYLIGHT
...
END:DAYLIGHT
END:VTIMEZONE
BEGIN:VEVENT
... VEVENT properties go here
END:VEVENT
END:VCALENDAR
As a matter of fact, since your event seem to be using zulu time, you can even skip the whole VTIMEZONE/STANDARD and simply go for
BEGIN:VCALENDAR
... VCALENDAR properties go here
BEGIN:VEVENT
... VEVENT properties go here
END:VEVENT
END:VCALENDAR
