Both RMarkdown and Quarto not showing plot inline

Using the default RMarkdown and calling plot(pressure), nothing shows beneath the code chunk in either Markdown or Quarto. Chunks are set to inline and anything that is NOT a plot shows, but plots do not.

If I call the plot(pressure) in the console, it prints to the viewer tab. The plots are also INCLUDED in the final rendering. They will just NOT PLOT INLINE. This is incredibly frustrating as the inline plots are so useful.

I have googled every possible combination of things that I can think of and I have not found any explanation for this.

I recently updated RStudio from the 2021 version to the most recent. I never had problems before and I don't particularly want to have to install multiple versions.

Thank you for reading
