devtools causes R 4.4.0 to freeze

Does anyone have any thoughts why devtools causes R 4.4.0 to freeze on my system (running Windows 10 Enterprise)? In RStudio (2024.04.1 Build 748) I get as far as:

library (devtools)
Loading required package: usethis

And then there's no response. Opening the RGui directly causing a freeze without any feedback.

The RStudio logfile shows:
