Why do we write "The shop is open" and not "The shop is opened"?
The passive voice is formed this way: verb + ed.
On the other hand, we write "The shop is closed".

Let's consider both examples:
The shop is closed.
The shop is open.
In this case, "open" and "closed" are adjectives. The word "closed" is an example of a participial adjective. It is similar to others such as "surprised", "intrigued", and "tired". These adjectives usually come from words with Latin roots. Other adjectives, such as "open" and "bright", have Germanic roots and do not take English forms requiring "ed" at the end.
Hope this helps!
