IRkernel installed, but still get "No kernel grammar for Null grammar found" in hydrogen

Hi,

I installed the IRkernel via the official instructions (using miniconda prompt with R.exe), and by adding the PATH variables necessary to bypass the 127 error when running IRkernel::installspec().

When I run jupyter kernelspec list in the conda command prompt, it returns

which shows that the ir kernel is not on the same path as the python one.

I dragged and dropped the kernel in my miniconda path and the file is there as we can see

The problem is that when I try running a simple R code in atom (1+1), it still gives me the error message “No kernel grammar for Null grammar found”

I wrote the IRkernel as such in hydrogen

Could you help me please to understand why hydrogen wont recognize the language? Thank you very much
