Kotlin Kernel in a constant cycle of die-and-restart

Hi,

I just installed BeakerX in my conda root environment.
As soon as I switch to the Kotlin kernel in Jupyter Notebook's BeakerX, I continuously see messages on the Jupyter UI as well as on the conda console indicating that the kernel has died and will auto-restart. The conda console also shows lots of exceptions. These happen even if I don't start typing anything.

Being completely new to all things here (conda, jupyter, beakerx, and kotlin), I'm not sure what other relevant info I need to mention here, and what's the best way to provide it. It's a Windows10. I'm attaching a snapshot of the (cyclically repeating) exceptions, and listing of my root env.
