ERROR! AppId <appid> launch failed (Steam client files corrupt)

[Chapter9]

Starting FEB 12 following a new Steam Client Update Released, when executing

app_run <appid>

command from steamcmd executable, I'm getting the following error:

ERROR! AppId <appid> launch failed (Steam client files corrupt)

Here is the script we are using to install the game:

@ShutdownOnFailedCommand 0
@NoPromptForPassword 1
force_install_dir "{{key `app/local/install_dir` | js}}"
login {{ .Data.username }} {{ .Data.password }}
app_update 228980
app_update {{ .Data.app_id }} -beta {{ .Data.beta }} -betapassword {{ .Data.beta_password }} validate
quit

Here is the script we are using to run the game:

@ShutdownOnFailedCommand 0
@NoPromptForPassword 1
force_install_dir "{{key `app/local/install_dir` | js}}"
login {{ .Data.username }} {{ .Data.password }}
app_run {{ .Data.app_id }} 0 "{{ key `app/common/arguments` }} {{ key `app/local/arguments` }}"
quit

My investigation leaded me to believe that the steamcmd manifest file wasn't updated to reflect the new Steam Client.
