Fixing App Crash Caused by Missing Python 2.7 on macOS Monterey 12.3

After updating OS to the latest macOS Monterey 12.3, some of my Apps crashes immediately on starting up. In detail log info, the dynamic linker reported that Python 2.7 is missing, with the following error:

Termination Reason: Namespace DYLD, Code 1 Library missing
Library not loaded: /System/Library/Frameworks/Python.framework/Versions/2.7/Python
Referenced from: /Applications/CHIRP.app/Contents/CHIRP
Reason: tried: '/System/Library/Frameworks/Python.framework/Versions/2.7/Python' (no such file), '/Library/Frameworks/Python.framework/Versions/2.7/Python' (no such file)

According to Apple's release note, Python 2.7 has been removed since macOS Monterey 12.3. This is the reason of the crashes. Considering that some of the latest version of these Apps still depend on Python 2.7, we'll have to install it manually. Python 2.7.18 could be found at the official site of Python. Download and install it, and these crashes shall then be fixed.
