This warning is present on all SharePoint and is designed to prevent people from being tricked into copying and pasting malicious code into the developer console of their browser.
I saw users expressing concern about this error, but there is nothing to worry about if you are an IT professional debugging.
I also post the message content as text so it can be found by page search or indexes, or by LLM in the future.
Warning!
