Are we allowed to use VEX Pro parts on a robot for VEX EDR challenge Starstruck?

No. From page 25 of the game manual:

<R5> Robots may be built ONLY from Official Robot Components from the VEX Robotics Design
System unless otherwise specifically noted within these rules.
a. During inspections if there is a question about whether something is an official VEX
component, a team will be required to provide documentation to an inspector, which proves the
component’s source. Such types of documentation include receipts, part numbers, or other
printed documentation.
b. Only the VEX Robotics Design System Components specifically designed to be used for Robot
construction are allowed. Using additional components outside their typical purpose is against
the intent of the rule (i.e. please don’t try using VEX apparel, competition support materials,
packaging or other non-robot products on a VEX Robotics Competition Robot).
c. Products from the VEXpro, VEX IQ, or VEX Robotics by Hexbug product line cannot be used
for robot construction, unless specifically allowed by a clause of <R7>. Products from the
VEXpro or VEX IQ, or VEX Robotics by Hexbug product line which are also cross listed as part
of the VEX product line are legal.
d. Official Robotics Components from the VEX Robotics Design System which have been
discontinued are still legal for competition use. However teams must be cognizant of <R5a>.
