Same

In Scrap\libs\SecureTabs-2.0\SecureTabs-2.0.lua modifying the line

Lib.template = PanelTabButtonMixin and 'PanelTabButtonTemplate' or 'CharacterFrameTabButtonTemplate'

to

Lib.template = PanelTabButtonMixin and 'TabButtonTemplate' or 'CharacterFrameTabButtonTemplate'

will make the addon work again, although the Scrap button will look a bit weird.
