It seems that the build always runs into network problems when installing yarn dependencies only on Windows.

That removed the info message, however the install is still pretty slow. It takes multiple minutes to install dependencies (the project certainly doesn’t have THAT many dependencies, and it’s quite a bit faster on my local machine with home internet speeds)
Thanks for the info. The Windows filesystem seems to be a bit slower, although we still have lots of tuning and improving yet to do. Caching is disable for all windows builds for the time being while we update some of our code to work with Windows. We hope to have it available next week.
For the time being I would class the initial issue as resolved, although we should document this, or apply the yarn timeout ourselves so others don’t need to.
I can confirm, disabling Windows Defender actually allowed my Windows job to complete well within the 50-minute limit. Everything from casher to MSYS2 installation to git submodule update --recursive on Boost was super-fast.
