Icons not displaying, google chrome extension

Question

I recently created a new extension which I'm still working on, and a thing I cant seem to get working is the extension icon, it isn't displayed in the extensions page or toolbar. Here is my manifest file code:

  "manifest_version": 3,

  "name": "shrekistan",
  "description": "This extension changes everybodys pfp's to shrek",
  "version": "1",

  "host_permissions": [
    "http://meet.google.com/*"
  ],

  "icons": { "16": "icon16.png",
    "32": "icon32.png",
    "48": "icon48.png",
   "128": "icon128.png" },    
            
   "content_scripts": [
            {
              "matches": ["https://meet.google.com/*"],
              "js": ["yourmom.js"]
            }],
          
          "background" : { 
            "service.worker" : ["background.js"]} 
} 

I tried multiple methods of adding icons from existing questions I found here (stack overflow) and none worked.

Seems to be an issue with the files. I used https://github.com/neglect-yp/chrome-extension-icon-generator to generate icons from the image, works fine.
