PHP 8.5 Breaks Upgrading

According to this report https://github.com/nextcloud/docker/pull/2580#issuecomment-5084361376 upgrading to 34.0.1 and above fails.
I get this error :

As mentioned here I tested the 34.0.3 version but this issue still persists
when we downgrade the base image from php 8.5 to 8.4 the problem goes away

Start with the linked report and pull request, then inspect the Docker image's PHP base-image and extension configuration while comparing PHP 8.4 with 8.5. Reproduce the upgrade from 34.0.1 or later; done means the image upgrades successfully without the opcache loading warning or an incorrect version check.
