## Possible Solution (Not obligatory)
The Problem
The error occurs at line 81 of UnifiedConfiguration.py:

python

def getDefaultProductForTarget(target_name: str) -> tuple[str, bool]:
The issue is that the code is using tuple[str, bool] as a type hint, but the Python version being used (Python 3.8.4) doesn't support this syntax. In Python 3.8 and earlier, you must use Tuple from the typing module instead.

How to Fix It
The code should be:

python

from typing import Tuple

def getDefaultProductForTarget(target_name: str) -> Tuple[str, bool]:
# function body

## Context

## Your Environment

- Operating System and version:
- TX hardware:
- RX hardware:

Start at line 81 of UnifiedConfiguration.py and inspect how the bundled Python 3.8.4 runtime loads that annotation. Reproduce the failure by launching the flasher for the Nomad Gemini target, then verify that the flasher starts without the TypeError and can proceed with flashing.
