I broke it

[Mybiased]

Hello

I tried to create a custom theme, but when I placed the json file in the theme directory, and open the application I would get a blank image,

If I deleted it it would go back to normal, my mistake was restarting my pc, anyway now even after I deleted the file from the theme directory I still get the same blank screen, I have uninstalled and installed and it is just that blank screen.
