The properties tab and the components tabs looks so weird. It doesn’t shows the logos / small icons on the webpage. If you look carefully to the photo, you’ll understand what I’m talking about.
Your system is affected with unwanted virus. Just use one antivirus and restart your browser. I had the same problem few months back and now I fixed it just by above steps and found working well
Thanks everyone. I thought the problem was a virus or something that blocking the loading fonts of the kodular.io webpage. I installed some antivirus programs and disabled all the google chrome extensions. So I solved the problem. Thanks for helping me!
