Install handler failed for the extension: permission denied

Hi team,
Running custom script extension on Oracle Linux (8.5) spits out this error in the portal. The VM was some time ago, and trying to install agents on it.
What could be the possible fix?
[{"code":"VMExtensionHandlerNonTransientError","message":"The handler for VM extension type 'Microsoft.Azure.Extensions.CustomScript' has reported terminal failure for VM extension 'cse-install-agents' with error message: '[ExtensionOperationError] Non-zero exit code: 126, /var/lib/waagent/Microsoft.Azure.Extensions.CustomScript-2.1.7/bin/custom-script-shim install\n[stdout]\n\n\n[stderr]\n/bin/sh: /var/lib/waagent/Microsoft.Azure.Extensions.CustomScript-2.1.7/bin/custom-script-shim: Permission denied\n'.\r\n \r\n'Install handler failed for the extension. More information on troubleshooting is available at https://aka.ms/VMExtensionCSELinuxTroubleshoot'"}]}

Inizia esaminando il percorso custom-script-shim segnalato e l’output VMExtensionHandlerNonTransientError su Oracle Linux 8.5. Segui la VM Extension Custom Script Linux troubleshooting guidance collegata e riproduci il problema di installazione dell’handler, se possibile. Il lavoro è completato quando sono state identificate una causa verificata e una correzione documentata per exit code 126 e l’errore permission-denied.
