JSON Parse Error When Using SFDX Commands (SFDX In Command Pallet Throws Different Error)

[ahardyGitHub]

Summary

CLI Commands abruptly stopped working as expected both using Git Bash and the point-and-click tools in VS Code.

In Gitbash, a command will return the error "JsonParseError: Unexpected end of JSON input".
Using point and click Command Palette commands, for example, "SFDX: Create Apex Trigger" will give an error pop-up message that says, "Command 'SFDX: Create Apex Trigger' resulted in an error. Command sfdx.force.apex.trigger.create' not found"

Steps To Reproduce

1. Open Salesforce DX project in VS Code
2. Attempt to run a DX command using Git Bash

OR

1. Open Salesforce DX project in VS Code
2. Attempt to any SFDX command using the Command Pallet results in error: "Command 'SFDX: [Action Name]' resulted in an error. Command sfdx.force.apex.trigger.create' not found"

Expected result

Commands operate as expected and how they have previously operated

Actual result

Git bash command results in error: "JsonParseError: Unexpected end of JSON input"
Command Palette SFDX Command result in pop-up error message: "Command 'SFDX: Create Apex Trigger' resulted in an error. Command sfdx.force.apex.trigger.create' not found"

Additional information

This issue is happening only on my Windows 11 laptop, across multiple projects. All of these projects previously worked without issue.

I have tried uninstalling and reinstalling CLI, but the errors remain.

The issue started yesterday morning after I ran sf config set target-dev-hub=myScratchOrg -g

No system updates had been run between when it was last working and stopped.

@ahardyGitHub that seems like the CLI is trying to read a corrupted json file (could be auth/config).

if you run sf org list do you see a warning like Warning: The auth file for <username> is invalid.?
