You are not authorised to fix this issue. A contribution from the brand owner or an authorised reseller is required to resolve this issue and activate the ASIN. If you are the brand owner or an authorised reseller for this brand, please apply for the appropriate role for this brand in Amazon Brand Registry.
I am sorry to hear that you are experiencing issues with suppressed listings. Unfortunately, as you know, once a listing gets search suppressed no one can see it unless you manage to address the reason for its suppression.
Amazon will typically require that you fill mandatory attributes in order to have the supressed listing reactivated. In your case, the missing unit count is a newly required attribute. However, since Aamzon requires that the listing is managed by the rights owner, you won’t be able to have the listing fixed and reactivated unless you manage to contact the brand directly.
The only think I can advise is to remove the listing as there are no means to have it restored by yourself.
