'Why am I getting this error after I deploy ma app?

I tried putting various combinations of meta tags, like:

<meta
  http-equiv="Content-Security-Policy"
  content="default-src; script-src-elem 'self'; font-src; 'self' data;"
/>

<meta
  http-equiv="Content-Security-Policy"
  content="default-src; script-src-elem; 'self'"
/>
<meta Content-Security-Policy: font-src *.example.com; />

but nothing seems to work. I don't even understand this error, so how could I know what to do?! Locally I'm not having any issue, only when I deploy. I even tried different deployment platforms, and still I get the same result. The sma e thing in incognito window. I read that the extension Grammarly can produce these errors, so I disabled it. Still, the same result.

These are the errors I'm talking about:
