Salesforce Plugin stopped working and sits on the Loading screen forever

I’m attempting to open the SalesForce plugin, which sits on the Loading screen forever.

In the mautic var/logs I could find the following:

[2024-02-26 06:06:34] mautic.CRITICAL: Uncaught PHP Exception Symfony\Component\Debug\Exception\FatalThrowableError: "asort(): Argument #1 ($array) must be of type array, null given" at /home/forge/mymauticsite.com/public/plugins/MauticCrmBundle/Integration/SalesforceIntegration.php line 357 {"exception":"[object] (Symfony\\Component\\Debug\\Exception\\FatalThrowableError(code: 0): asort(): Argument #1 ($array) must be of type array, null given at /home/forge/mymauticsite.com/public/plugins/MauticCrmBundle/Integration/SalesforceIntegration.php:357)"} {"hostname":"my-mautic-server","pid":262466}

Just in case, I have a staging site with the same version (v4.4.10
) pointing to the salesforce sandbox and it’s working fine.
