my numbers isnt opening and wont allow me download latest app

Reboot into Safe Mode, and open the Mac App,Store and download from there, or try to. Safe Mode disables various add-ons, rebuilds caches, and can sometimes clear transient problems.

If that doesn’t work, post the EtreCheck data here. Open a new reply, press the button that looks like a printed page to get a text input box big enough for the hardware and software configuration report. That’ll provide some info on the configuration.
