Run Task Freezes for some Variable References

[shengchao-lin]

When variable reference is used that relates to the current file, e.g., ${file}, ${fileBasename}, etc, the run task freezes. However, a simple echo does not. See the example below. Task "My C++ build" hangs but "echo" does not.

When freezing, the terminal tab shows:

If task "echo" is ran first, launched the terminal tab, and ran successfully, then task "My C++ build" can ran successfully too.

Additionally, when the "${workspaceFolder}/${fileBasename}" is replaced with something like "${workspaceFolder}/main.cpp", the task "My C++ build" runs successfully.

What could be the issue here?
