Weird font displaying in Plots

I am not sure what happened, since I have been using Plots for years without too many issues. But since a few days ago, my plots have been displaying this strange font. All I remember doing right beforehand was updating the Plots package (in JuliaPro 1.4.1). Does anyone know how to get back the original font (it looked like Arial)? I tried uninstalling and reinstalling Julia and the Plots package too, without any success. Thank you in advance!

Here is what the font looks like:
