I'm facing the same issue while trying to update to PHP 8.4.

Could this ticket be reopened? This is still an issue for me on php 8.4.7

Could you please post some logs?

I'm sorry, this was when using the shopify PHP template repo: https://github.com/Shopify/shopify-app-template-php

It's most likely not relevant to this one. That one will just have their PHP & Laravel versions updated. The error message was however exactly like OP posted.
