Is the long, blue WindowsDebugLauncher.exe message that prints when I run C/C++ code in VS Code an error?

When I run my C program on VS Code through cpptools (the Microsoft C++ extension for VS Code), I always get this long, blue-colored message in the terminal. Sometimes the code runs and sometimes it doesn't run. It looks like an error message(?)- especially the part that says "stderror". I tried to uninstall vs code and then reinstall it but it didn't help. Is this an error message? If so, how can I fix the problem?

This is the message: 'c:\Users\me\.vscode\extensions\ms-vscode.cpptools-1.20.5-win32-x64\debugAdapters\bin\WindowsDebugLauncher.exe' '--stdin=Microsoft-MIEngine-In-2hzunawp.5jd' '--stdout=Microsoft-MIEngine-Out-4c1l0eot.hlz' '--stderr=Microsoft-MIEngine-Error-f1z5ijur.qi1' '--pid=Microsoft-MIEngine-Pid-0dxp5msa.4og' '--dbgExe=C:\MinGW\bin\gdb.exe' '--interpreter=mi'

Here's what it looks like on my screen:

A similar thing happens when I try to run C++ code using cpptools.

It's not an error. That's the command that the cpptools extension uses to start debugging when you tell it to start debugging. The part that says "--stderr=Microsoft-MIEngine-Error-f1z5ijur.qi1" is specifying a file for the standard error stream when debugging.

The ^C (ctrl-c / interrupt key) you see in between them is an automatic interrupt key inserted by VS Code that I explain to some depth in my answer to VS Code 1.88 inserts ^C before running a debug configuration again. Why?.

Your code running sometimes and sometimes not is probably unrelated to this. Maybe you have compilation / link / runtime errors.
