Comment (by usmanshb):

 Thank you for reporting this. The error usually occurs when some output
 (like extra spaces or text) is sent before PHP headers. It’s likely caused
 by a change or whitespace in the WordPress core file or a plugin.

 Please avoid editing core files directly. Try disabling all plugins and
 switching to a default theme to check if the issue persists. If the error
 disappears, reactivate them one by one to find the cause.

 Downgrading to 6.6 is fine temporarily, but once the source is found, you
 can safely upgrade again.
