A similarly looking problem exists for multiple packages. It may be 
related to some setup on the checking system or some more general 
problem not specifically related to your package, I didn't yet have time 
to diagnose.

For now there is a virtual machine setup (you can install a 
free-for-testing Windows virtual machine). A link is in the README or here
https://developer.r-project.org/Blog/public/2021/03/18/virtual-windows-machine-for-checking-r-packages/index.html 


This is available for package developers to debug issues with their 
packages, but in this case it really may be something unrelated to your 
package, so unless you wanted to volunteer your time diagnosing this, 
please ignore.
