I have been struggling with this same issue and finally found #2 patch works for me!

My error was:
Uncaught PHP Exception Twig\Error\LoaderError: "Template "modules/contrib/ui_patterns/modules/ui_patterns_library/templates/pattern-page-body.html.twig" is not defined." at /code/web/modules/contrib/ds/templates/ds-entity-view.html.twig line 10
