Kernel logos are not displayed in Windows 11 JupyterLab 4.3.0

[RRosio]

Originally reported in jupyterlab/jupyterlab#16932, user running JupyterLab 4.3.0 on a Windows 11 system through Anaconda Powershell Prompt. Sample images demonstrating missing icons are included in original issue.

"""

The notebook icon on the startup page cannot be displayed normally, but it does not affect the use of functions.

The version of my jupyter lab is 4.3.0, running on the windows11 system. I installed jupyterlab through Anaconda.

After opening jupyter lab through Powershell, it can be started normally. However, the startup page cannot display the notebook option icon normally. I want to know how to solve this problem.

"""

---

I was able to replicate this after installing nb_conda_kernels on a clean anaconda3 install with a test environment with JupyterLab 4.3.0 installed.

Console Output

Default kernel not found, using 'conda-base-py'
