&"warning: GDB: Failed to set controlling terminal: Operation not permitted\n"

I'm currently using vscode on ubuntu to write and debug a simple c program. I've updated gdb to the newest version(9.2-0ubuntu1~20.04.1). Whenever I click the debug button a "Permission Denied" error is shown.

Here's a screenshot of the error message

How do I resolve this error so that I can debug my C program with GDB and VSCode? I would appreciate it. The problem has bothered me for days and I can't figure it out myself.

This code snippet below is my launch.json file.
