We have a CI test pipeline in which R package ggraph is installed from CRAN (in its most recent version).
From today on, our pipeline fails to install package ggraph for R versions 3.6. and 4.0 (but succeeds installing it for more recent R versions 4.1, 4.2, 4.3).

As far as I have seen, none of the package updates has changed its requirements regarding the supported R versions. When looking at your repository, I can see that also your own CI pipeline fails for R versions 3.6 and 4.0 and it breaks when compiling package statnet.common version 4.9.0 (here). But statnet.common version 4.9.0 has been released almost one year ago. So, I assume that ggraph imports statnet.common and ggraph version 2.2.0 cannot be installed in R versions 3.6. and 4.0 because of an internal error in ggraph that is somehow related to how ggraph tries to build statnet.common. Am I right with my assumption?

Could you please have a look at this problem and potentially find a solution such that ggraph becomes availabe and installable for R versions 3.6 and 4.0 again?
Thanks in advance!
