Support question

I am seeing the below error when analysing a file:

[obfuscated].php
--- consumed 0 B, total 214.5 MB
Result cache was not saved because of non-ignorable exception: Could not read file: 
 ------ ----------------------------- 
  Line   [obfuscated].php  
 ------ ----------------------------- 
         Could not read file:         
 ------ ----------------------------- 

The issue occurs when the file uses a function which exists in an Ioncube encoded file. For example,

<?php

function foo() {
    ioncubeEncodedFunction();
}

If I delete the function usages, the issue goes away.

I have a PHPStan bootstrap file and have checked that ioncubeEncodedFunction exists using function_exists.

PHPStan logs no further output beyond what is mentioned above, even when --debug and -vvv are used.

Please can you help me to debug this further?
