title: Plots not loading in R console, using ggplot
body: <p>Whenever I run code chunks containing plots within my project, it fails to load but doesn't display any error message, as if the console is frozen and then eventually times out. I have ran this code script 20 times or more and it all worked fine, but now for some reason unknown it just won't work.</p>
  <p>I have tried:</p>
  <ul>
  <li>Restarting R</li>
  <li>Reinstalling R</li>
  <li>Updating and installing packages again</li>
  <li>Running different Rmd's/projects which have been run before, (they don't work either)</li>
  </ul>
  <p>Any other code chunk will execute fine and other packages all seem to be operating as usual. I am currently running the latest Rstudio 4.1.3 build 492.</p>
  <p>Here is my code anyway:</p>
  <pre><code>budget_revenue &lt;- ggplot(data = filtered_movies2) + 
    geom_point(mapping = aes(x = budget, y = revenue, colour = genre_1)) + 
    facet_wrap(~ genre_1, nrow = 2) +
    labs(title = &quot;Budget and Revenue by Genre&quot;, x = &quot;Movie Budget&quot;, y = &quot;Gross Revenue&quot;) +
    scale_y_continuous(&quot;Gross Revenue&quot;, 
                         breaks = scales::breaks_extended(8),
                         labels = scales::label_dollar()) + 
    scale_x_continuous(&quot;Movie Budget&quot;,
                       breaks = scales::breaks_extended(5),
                       labels = scales::label_dollar()) +
    theme_minimal() +
     theme(axis.text.x = element_text(angle = 45, vjust = 0.5)) +
    theme(legend.position = &quot;none&quot;)
    
    
    budget_revenue +
      scale_colour_viridis_d() 
  </code></pre>
