Hi,
To modify the default view of projects in Odoo, override both 'ir.actions.act_window' records (open_view_project_all and open_view_project_all_group_stage) to set the view_id to project.view_project, ensuring it opens the project form view.
<record id="open_view_project_all" model="ir.actions.act_window">
<field name="name">Projects</field>
<field name="res_model">project.project</field>
<field name="domain">[]</field>
<field name="view_mode">form,kanban,tree</field>
<field name="view_id" ref="project.view_project"/>
<field name="search_view_id" ref="project.view_project_project_filter"/>
<field name="help" type="html">
<p class="o_view_nocontent_smiling_face">
No projects found. Let's create one!
</p>

Create projects to organize your tasks. Define a different workflow for each project.

Projects contain tasks on the same topic, and each has its own dashboard.

</record>
Hope it helps
