在我将python扩展回滚到以前的版本（v2020 .7.96456），那么问题就消失了，调试器可以前进到下一行代码，然后可以正常工作。

After I rolled back the python extension to its previous version (v2020.7.96456), then the problem is gone and the debugger can advance to next line of code and then works properly.

尽管我没有确凿的证据证明为什么要使用最新版本（v2020。 8.101144）导致调试器停止接受用户输入，至少回滚到以前的版本可能是一种临时补救措施，直到以后的修订版本解决了该问题为止。

Though I have no hard prove that why does the latest version (v2020.8.101144) cause the debugger stoping accepting user input, at least rolling back to a previous version can be a temporary remedy, until future revisions address this issue.
