SassC::SyntaxError: Error: You may not @extend selectors across media queries.
       Use "@extend %responsive-container-xl !optional" to avoid this error.
        on line 62:7 of vendor/bundle/ruby/2.6.0/gems/bootstrap-4.5.0/assets/stylesheets/bootstrap/mixins/_breakpoints.scss, in mixin `media-breakpoint-up`
        from line 23:14 of vendor/bundle/ruby/2.6.0/gems/bootstrap-4.5.0/assets/stylesheets/bootstrap/_grid.scss
        from line 16:9 of vendor/bundle/ruby/2.6.0/gems/bootstrap-4.5.0/assets/stylesheets/_bootstrap.scss

I think here
https://github.com/twbs/bootstrap-rubygem/blob/v4.5.0/assets/stylesheets/bootstrap/_grid.scss#L34
we are using @extend, inside @media
https://github.com/twbs/bootstrap-rubygem/blob/v4.5.0/assets/stylesheets/bootstrap/mixins/_breakpoints.scss#L61

Research direction

Start with assets/stylesheets/bootstrap/_grid.scss around line 34 and mixins/_breakpoints.scss around line 61, then reproduce the reported SassC compilation error with the listed Bootstrap 4.5.0, SassC 2.4.0, Ruby 2.6.6, and Rails 5.2.4.3 versions. Done means the stylesheet compiles without the cross-media-query @extend error.
