Errors in console shown as objects

I got a weird error I never had on other computers that appears only on my website (other websites are showing errors as usual without objects).

Image that describes the error

I know how to fix the specific reason for the error, but it is very disturbing that it looks like an object instead of like a message as it has always been to me.
Using Angular if it can lead for the reason.

Tried multiple browsers, tried to change google chrome settings, didn’t help.
