After restoring a database upgraded from Odoo 14 to Odoo 16 we receive the Style error.

Style error

The style compilation failed, see the error below. Your recent actions may be the cause, please try reverting the changes you made.

Could not get content for /bi_view_editor/static/src/css/bve.css.

Uninstalled OCA / reporting\-engine /bi_view_editor,\ upgraded\ all\ modules\ in\ the\ database,\ regenerated\ asset\ bundles\ and\ sent\ the\ database\ away\ for\ upgrade\.

This\ did\ not\ clear\ the\ issue\.\ Still\ got\ the\ same\ style\ error\.

After\ selecting\ OK\ for\ the\ style\ error\ Odoo\ dashboard\ is\ not\ visible\. \ Blank\ page\ with\ none\ of\ the\ application\ icons\.

Restored\ the\ upgraded\ dump\ to\ Odoo\.sh\.  

This\ allowed\ access\ to\ the\ Odoo\ Dashboard\ but\ all\ the\ style\ sheets\ are\ in\ error\.

If\ for\ example\ sale\ order\ form\ selected\ get\ message\.

How\ can\ the\ backend\ assets\ be\ forced\ to\ regenerate\ either\ at\ Odoo\ 14\ before\ database\ sent\ for\ upgrade\ or at\ Odoo\ 16\ after\ the\ upgrade\?

Or\ How\ can\ the\ reference\ to
