Debugger crashed after program done.

[nanixne]

• VSCode Version: 1.47.x (1.46.x are all fine)
• OS Version: Windows 10
• Node 14.3.0 or later, (14.2.0 or earlier are all fine)

Steps to Reproduce:

1. node.js is 14.3.0 and later (14.6.0), 14.2.0 do not have this issue
2. and when I just direct run node app.js or node --inspect app.js in command line (as well as VSCode terminal) , everything goes well. (app.js is my program)
3. run app.js in vscode debugger by press F5, code run correctly, but it has some error messages after my program last output. sorry I cannot provide my app.js code, but it seems after I comment some await fsPromise.writeFile, the messages are gone.
   all these ONLY happen when I run app.js in VSCode debugger[1], VS Code 1.47.x[2] and Node 14.3.0[3]. (all three need meet together)

error message is

Debugger listening on ws://127.0.0.1:51841/4fb8eedf-3d50-4eac-911a-79b7f1a06526
