Blacked out ggplot plots when rendering Rmd

Hi!

I updated my operating system and had to reinstall R, RStudio and all the packages I use. With the new version of this, when I render an html using Rmarkdown all my ggplots have a black background when I did not specify so. They look like this:

Here is the sessionInfo() of what I'm running:

Update: I checked an old html that I created before the update and I saw that I used ggplot2 version 3.5.1 and rmarkdown version 2.28. I downgraded to these versions of ggplot2 and rmarkdown and the problem is still there. This makes me think maybe it's because of the newer version of RStudio, but I'm not sure.

New update: I upgraded to RStudio version 2025.05.0 Build 496 and now the plots look as they should
