I have an application file of the Catalina installer, I want to clean install Catalina on this Mac. When I open the application file absolutely nothing happeneds. Does anybody have any idea as to why this could be or how I can solve this problem?

You may need to move the install package to an external thumb drive and then boot from that. See instructions here:
