I just ran into this problem in RStudio (2026.04.0+526) with the latest version of R (4.6.0) on a Windows 11 laptop. It hangs when trying install a BioConductor package if it can only be installed from source. The command in question yesterday was
BiocManager:: install("AnnotationHub")
It prints the message that the package requires compilation, but it fails to print the prompt that asks for permission to do that. I eventually opened another R interface (Emacs Speaks Statistics in Emacs) and was able to install the package.
