After restarting my computer, running OS X 10.8.5, the old GitHub client suddenly stopped working with the following error message:
You can’t use this version of the application “GitHub Desktop” with this version of OS X.
You have OS X 10.8.5. The application requires OS X 10.9 or later.
However, the very same application had been working previously with no issues. Is any way I can restore it?
I have downloaded the same application again from this direct download link,
but now it is still blocked from starting with the same message, by what looks like only a system lock outside the application.
Is there any way to bypass that blocking setting and start the application?
Here is a screenshot of the message:

According to Updating GitHub Desktop the client updates itself automatically:
It appears that Github has updated their build toolchain server to a newer version of Xcode not supporting Lion.
You need to stay on the old version.
You may want to contact Github to get the newest build you can still use.
