Warning: Can't call setState on a component that is not yet mounted.

[AnatoliiCubex]

When trying to do some logic , after click nothing is happening and I receive these errors in console
Type of flow that Im trying to use and get this error:

1. change label fontsize
2. adding hyperlink link
3. clicking on radio in multiple choice

This is the code of my component, without any additional props.

return (
      <Box sx={{ width: '100%', maxWidth: '1250px', margin: '0 auto', py: 5 }}>
         <ReactFormBuilder />
      </Box>
   );
