Could you kindly create a new user with an Editor user role and recheck the issue?

We'll check and get back to you soon. 

Please check here: https://wordpress.org/documentation/article/roles-and-capabilities/#summary-of-roles

• Super Admin – somebody with access to the site network administration features and all other features. See the Create a Network article.
• Administrator (slug: ‘administrator’) – somebody who has access to all the administration features within a single site.
• Editor (slug: ‘editor’) – somebody who can publish and manage posts including the posts of other users.
• Author  (slug: ‘author’)  – somebody who can publish and manage their own posts.
• Contributor (slug: ‘contributor’) – somebody who can write and manage their own posts but cannot publish them.
• Subscriber (slug: ‘subscriber’) – somebody who can only manage their profile.

We have an intranet and some users are Editors. They can't upload images and they don't have a custom role as you can check.

Thanks!
