Did not check deeper but log is

PHPStan crashed in the previous run probably because of excessive memory consumption.
It consumed around 26 MB of memory.


To avoid this issue, allow to use more memory with the --memory-limit option.

Seems like a legit bug in XHProfLib

Fatal error: Class Drupal\xhprof\XHProfLib\Report\DiffReport contains 6 abstract methods and must therefore be declared abstract or implement the remaining methods

Yeah, the problem is in the code:

<?php

namespace Drupal\xhprof\XHProfLib\Report;

/**
 * Class DiffReport
 */
class DiffReport implements ReportInterface {

  public function getReport() {
    // TODO: Implement getReport() method.
  }

}

It would be best to remove this file, or mark it as ignored.
