Failed opening required -- from class-php-autoloader.php

### Impacted plugin

Jetpack

### Quick summary

We are seeing on the Atomic platform multiple fatal errors where the Autoloader "Failed opening required" files. The interesting aspect is that the file it fails to find can be non-jetpack plugins.

```
PHP Fatal error: require(): Failed opening required '/srv/htdocs/wp-content/plugins/google-listings-and-ads/src/Proxies/Tracks.php' (include_path='/:.') in /wordpress/plugins/jetpack/13.1-a.9/vendor/jetpack-autoloader/class-php-autoloader.php on line 90

### Steps to reproduce

Unknown -> can't reproduce on my test sites spun up on various pools.

### A clear and concise description of what you expected to happen.

No Fatals errors should be triggered by Jetpack code flows.

### What actually happened

_No response_

### Impact

Some (< 50%)

### Available workarounds?

No but the platform is still usable

### Platform (Simple and/or Atomic)

Atomic

### Logs or notes

Errors can be see in at-php-errors logstash name=jetpack

Start with vendor/jetpack-autoloader/class-php-autoloader.php at line 90 and compare the reported failures with the Atomic at-php-errors Logstash entries. Trace the calls from jetpack-boost/app/modules/optimizations/minify/class-minify-js.php and determine why missing files from Jetpack Boost and other plugins reach this loader. Done means the failure is reproduced or explained and the affected code flow no longer triggers these fatal errors.
