String conversion error: Illegal byte sequence encounted in the input.

I had successfully working project on 3.6 monogame version but when I updated it to 3.7 version I get such error:

We cannot help unless we can see the line it’s crashing on.

Also your explanation is not clear. You say it does not start. But it does but then crashed therefore it starts.

That looks really early in the games run line 18 ?
Does a blank monogame project start up ?
The error itself bad byte sequence could pertain to a file in the wrong encoding.

I created a blank project Cross Platform DesktopGL later and got the same error but it was not displayed on dialog and was displayed on text code. I wrote about this case on giiter today
