Catalina update : Wont open App Store Anyone else???

Since the update to Catalina, my iMac is acting weirdly. I can't update anything and when I try to open the App Store, it just opens to a white screen and won't do anything.

I have tried:

Logging out of Apple ID

Opening Facetime

Creating another User

Using a different Apple ID

Deleting cookies, cache and everything else listed in the troubleshooting guide

Running eTrecheck

STILL won't open.

Is anyone else having this problem?

I had the exact same problem and found an answer that worked for me here:

https://www.reddit.com/r/MacOS/comments/enmnk6/app_store_completely_not_working_for_macos/

I opened up the Keychain Access app, then Preferences, then Reset My Default Keychains.

As soon as I did this it immediately worked, don't understand why or why this isn't anywhere on the Apple support forums.
