Solution
Make sure any previous opened Chrome debugging windows are closed before you start a new debugging session
Explanation
When I started debugging from VS2017 a new Chrome window opened and when I stopped debugging the Chrome debugging window were shut down and then I could start debugging again.
If the Chrome debugging window wasn't shut down upon debugging stop for whatever reason, and I started a new debugging from VS then it opened a new tab in the previously opened Chrome debugging window, and I had the error and couldn't start debugging.
So I closed the debugging window manually before I started debugging and it worked again.

The problem solved by following setting
VS-2017 -> Tools -> Options -> Debugging -> General: Uncheck/Disable the "Enable JavaScript Debugging for ASP.NET (Chrome and IE)" option 

I tried the other options provided above such as Restart VS-2017, closing browser opened earlier but that didn't solved this problem. I have installed VS-2017 Community Edition one week back only.

blocks|key|2809092|text|我想分享我的解决方案。只需在IIS中重新启动应用程序和应用程序Poll。希望它能帮到你。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|2809093|entityMap^0|B|6|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

I want share my my solution. Just restart your Application and App Poll in IIS. Hope it helps you.

I have a problem with my IDE. Simply in asp.net web application project when I try to start debugging with Chrome, the <a href="https://i.stack.imgur.com/prHhc.png" rel="nofollow noreferrer">problem </a>shows up.

The problem doesn't occur selecting Edge browser for debugging by the way.

<a href="https://i.stack.imgur.com/prHhc.png" rel="nofollow noreferrer">https://i.stack.imgur.com/prHhc.png</a>

Also I have no problem when I unclick "Enable javascript debugging for ASP.NET (Chrome and IE)".

我的IDE有问题。简单地说，在asp.net web应用程序项目中，当我尝试使用Chrome进行调试时，就会出现。顺便说一下，选择边缘浏览器进行调试时不会出现问题。当我取消点击“启用ASP.NET (Chrome和IE)的javascript调试”时，我也没有问题。
