as a quick test, can you try

install https://en-gb.wordpress.org/plugins/code-snippets/

and add this code

function rew_astra_bbpress_fix ($value) {
		if (bbp_is_single_user()) return false ;
		if (bbp_is_search()) return false ;
		if (bbp_is_topic_tag()) return false ;
		if (bbp_is_single_view()) return false ;
return $value ;
}

add_filter ('astra_single_layout_one_banner_visibility', 'rew_astra_bbpress_fix', 50) ;
