Ted here from Shopify, thanks for posting your query and for sharing an example of the error you're seeing!
Have you recently set up Shopify Payments? Were you asked to submit documentation such as a government-issued ID or similar for review? If so, have you submitted these documents and do you know when they were submitted? It can take up to 1-10 business days for the Shopify Payments team to review this information depending on what they've asked for and if they need to verify these details with our banking partners.
It could also be due to the products you're selling. For example, you might be selling a prohibited product that can't be sold using Shopify Payments as mentioned here. If this is the case, by any chance did you see another red banner in your admin asking for reseller documentation?
If there is anything else I can help you with, please let me know, I'm happy to help!
