Hi all,
First of all I appreciate all of the work that has been and is being put into making GPU programming possible in Julia. 
I am new to GPU programming, and I basically just installed CUDA.jl and tried running ‘]test CUDA’ and I get the error below. Am I doing something wrong? The reason I write is that I got this same error on two machines, but I thought the first machine was broken. But now I got the same error on my brand new desktop computer, so I think this might be an error within the package?
I am on Windows 11. My previous machine which I thought was broken was running the Pop!_OS Linux distro, but gave the same error. My system setup:

The error message:
