R kernel in jupyter lab: "no kernel"

Hi there! I’ve tried everything and I can’t make R kernel work in jupyter lab. I have it in my jupyter lab workspace, it seems available, I select the kernel and it reads “no kernel”. If you run the cells, nothing happens. How can I fix this? Could it be that something is missing in miniconda environment? I appreciate your time in helping me with this.

Cheers,
Denise
