Hello @vishvega,
I’m sorry to hear you’re running into problems getting this set up – I’m sure it is frustrating!
To recap, it sounds like you’ve gone through the setup wizard and are having some problems choosing a catalog, as well as an error displaying:
Catalogue is not associated with the shop tied to your Page or Instagram account.
After doing some digging on Facebook’s website I see that they say that your Commerce account, Instagram account, and Facebook Page must be connected to the same Business Manager.
Do you perhaps have different Business Managers? Additionally, do you have a Commerce account? Facebook has some step-by-step instructions here on where to check those settings on their end:

Alternatively, you may want to get in touch with Facebook Business Extension support in case they can provide additional information on the error messages you’re getting here: https://www.facebook.com/help/contact/552096935652452
On a separate note, I notice you have a fairly outdated version of WooCommerce, you are on 4.7.1 and 5.3.0 is available (WooCommerce Shipping & Tax is also a bit out of date). Keeping WooCommerce updated is always a good idea! As always, we recommend creating a backup of your site and making sure that the themes and plugins are compatible before updating. You can check out this update guide for more information.
I hope that helps, and if you have any further questions please let us know with a reply. Have a great day!`
