Hello,
I saw the screenshot you attached.
Please add widgets to the Shop page widget area under Appearance >> Widgets.
And disable the Shop filters from Theme Settings >> Products Archive >> Shop Filters.
Screenshot for Clarification: https://gyazo.com/e4754152903d5c5a208b571ce63aea88
And the Widgets Errors are WordPress problems not related to our theme.
Try to install Classic Widgets plugin to fix this problem for now https://wordpress.org/plugins/classic-widgets/
Regard’s.
