Sudden Issues Debugging Azure Functions in VS Code

Question

I have a large code base of Azure Functions (Typescript) that I manage using VS Code and the Azure Functions extension. I am using VS Code in WSL (Windows). I've been able to debug these functions in VS Code for a few years with no problems. However, I've started to notice odd behavior:

1. VS Code started not picking up code changes after stopping and restarting the debugger. I would have to manually run npm run build.
2. Hitting the "Stop" debugging button would not kill the process, and the function would keep running.
3. Now when I start debugging, I don't see the debugging toolbar (with stop, stepover, etc.). When I try to "dock" it using VS Code settings, it appears for a bit, then disappears. Breakpoints are no longer hit.

The above issues started after a few recent updates of VS Code. I'm at the point where I can't debug anything. Here are some things I've tried:

1. Checking launch.json and tasks.json to ensure everything is set up correctly. See below for current versions.
2. Used Copilot to generate a new launch.json (just created other issues).
3. Updating Azure Functions Core Tools and the Azure Functions extension.
4. Clearing all cache folders and restarting VS Code.
5. Re-installing VS Code.

launch.json:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Attach to Node Functions",
      "type": "node",
      "request": "attach",
      "port": 9229,
      "preLaunchTask": "func: host start"
    }
  ]
}

tasks.json:

{
  "version": "2.0.0",
  "tasks": [
    {
      "type": "func",
      "label": "func: host start",
      "command": "host start",
      "problemMatcher": "$func-node-watch",
      "isBackground": true,
      "dependsOn": "npm build (functions)"
    },
    {
      "type": "shell",
      "label": "npm build (functions)",
      "command": "npm run build",
      "dependsOn": "npm clean (functions)",
      "problemMatcher": "$tsc"
    },
    {
      "type": "shell",
      "label": "npm install (functions)",
      "command": "npm install"
    },
    {
      "type": "shell",
      "label": "npm prune (functions)",
      "command": "npm prune --production",
      "dependsOn": "npm build (functions)",
      "problemMatcher": []
    },
    {
      "type": "shell",
      "label": "npm clean (functions)",
      "command": "npm run clean",
      "dependsOn": "npm install (functions)"
    }
  ]
}
