Hello,
I hope you are doing well

Fix: Hide the product description on invoices by inheriting the invoice QWeb template and replacing line.name with line.product_id.name.

<odoo>                                                                                                                                                                                      
    <template id="hide_desc_invoice"                                                                                                                                                        
                inherit_id="account.report_invoice_document">                                                                                                                                 
      	​<xpath expr="//span[@t-field='line.name']" position="replace">                                                                                                                      
              <span t-esc="line.product_id.name or line.name"/>                                                                                                                               
        </xpath>
      </template>                                                                                                                                                                             
  </odoo>      

I hope this information helps you
