Not sure if the error is easy to fix or not, and I’m happy to provide any more relevant info.  
Running a NVIDIA RTX 4070 ti with up to date drivers and CUDA.jl master branch.

That’s only for the tests, CUDA.jl itself should work properly.  
Could you verify? In fact, please also open an issue, as we probably should just run the tests albeit with a warning at the top that some things may break.

Thanks for your response. That’s correct CUDA itself seemed to work fine with simple operations ( I didn’t test anything beyond arithmetic / Matrix multiplication), but the tests failed. I’ll open an issue on Github
