Hi @duarte aguiar ,
Based on the information you provided, it seems like the issue is related to the compatibility of the custom view with the modern experience in SharePoint Online.
One possible solution could be to try and recreate the custom view in the modern experience, which might be more compatible with the modern experience. Alternatively, you could try using a third-party tool or custom code to create a custom web part that displays the information with the necessary filters.
Another option could be to use the SharePoint Designer to modify the view and make it compatible with the modern experience. However, this would require some technical expertise and knowledge of SharePoint Designer.
In summary, the best option at present is to still use the classic experience.
