[Python] Jupyter Scheduler (JupyterLab Extension) Error: No such kernel named conda-base-py

I installed all apps (Jupyer Notebooks, Lab, etc.) from Anaconda. Then, I installed the Jupyter Scheduler extension to use on Jupyter Lab.

When I run a .ipynb in Jupyter Lab, it works fine. But when I try to run one on a schedule via the scheduler extension, I get the No such kernel named conda-base-py error.

I used "jupyter kernelspec list" on the anaconda prompt and got back:

Available kernels:
python3 C:\Users\qdbra\anaconda3\share\jupyter\kernels\python3


I checked the kernel.json file and it shows:

{
"argv": [
"C:/Users/qdbra/anaconda3\\python.exe",
"-m",
"ipykernel_launcher",
"-f",
"{connection_file}"
],
"display_name": "Python 3 (ipykernel)",
"language": "python",
"metadata": {
"debugger": false
}
}


I tried uninstalling and reinstalling ipython, a different browser to run jupyterlab, and a few other things to no avail.
