Unable to create new site using (hugo) Academic theme

I am new to blogdown and working my way through the fabulous resource to guide me. Unfortunately, I am unable to use the academic theme in hugo. To create a new site I have:

Created a new (empty) project in a brand new working directory.
Installed blogdown and hugo, as recommended
Tried to create a new site by running the following:

blogdown::new_site(theme = "gcushen/hugo-academic")

Unfortunately, I then encounter the following errors:

Error: Unable to find theme Directory: C:\Users\myusername\Documents\MyBlog\themes\academic

Error: Unable to find theme Directory: C:\Users\myusername\Documents\MyBlog\themes\academic

Error: Unable to find theme Directory: C:\Users\myusername\Documents\MyBlog\themes\academic

I also encounter the following:

Error in shell(cmd, mustWork = TRUE, intern = intern) : 
  '"C:\Users\myusername\AppData\Roaming\Hugo\hugo.exe" convert toYAML --unsafe' execution failed with error code 65535

Where am I going wrong? I also tried to use the guide on installing/ creating via RStudio but encountered the same issue. I am new to blogdown so would appreciate any assistance.

Thank you!

This is due to a breaking change in the hugo-academic theme. I have fixed it in blogdown a few hours earlier. Please try the development version:

remotes::install_github('rstudio/blogdown')

Restart R and create a new site with this theme again.
