To resolve the problem yopu need to find and edit a bit next files:

.../comfyui/custom_nodes/comfyui-crystools/web/styles.js

replace it with the same path in lower case

//utils.addStylesheet('extensions/ComfyUI-Crystools/monitor.css');

//utils.addStylesheet('extensions/ComfyUI-Crystools/monitor.css');
utils.addStylesheet('extensions/comfyui-crystools/monitor.css');

then reboot the server and refresh your page with Comfy. Now it should look like
