Build Process Hangs on Subsequent Builds After First Successful Run in VSCode

---

Describe the bug
The build process stops at the last line during the execution of the build command using west in VSCode. The issue occurs after the first successful build, and subsequent builds halt without completing. Restarting VSCode temporarily resolves the issue.

Please also mention any information which could help others to understand the problem you're facing:

• Target platform: ARM Cortex-M based custom board (customboard)
• Diagnostic steps:
  • Monitored resource usage.
  • Cleaned and rebuilt the build directory.
  • Ran the build process in an external terminal. (Problem does not occur here)
  • Disabled extensions in VSCode to identify potential conflicts. (No effects)
• Regression: Not confirmed. The issue was observed recently but hasn't been bisected to a specific commit.

To Reproduce
Steps to reproduce the behavior:

1. Execute the build command in VSCode:

   /path/to/venv/bin/west build -p -b customobc -- -DBOARD_ROOT=/path/to/project/root -DCONFIG_DEBUG_THREAD_INFO=y -DCONFIG_INIT_STACKS=y -DCONFIG_THREAD_STACK_INFO=y

2. The build process succeeds initially but fails on subsequent attempts, halting at the following line:

   -- Found GnuLd: /path/to/zephyr-sdk-0.16.5/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld.bfd (found version "2.38") 
   

Expected behavior
The build process should complete successfully on subsequent attempts without needing to restart VSCode.

Impact
This issue is a showstopper as it requires restarting the development environment frequently, disrupting the workflow and slowing down development progress.

As far as I know, we do not provide anything related to vscode?

Can you reproduce this problem on the command line? If not, I'd advice you to report this issue against vscode instead.
