So, the error comes from:

if (!file_exists($binaryPath) || !is_executable($binaryPath))

What about this suggestion: Ad a if(@is_readable($path)) to avoid the warning, befor the file_exists check? Works in both files ImageMagick6Preset.php and GraphicsMagickPreset.php Sorry that I don't have the knowledge to make it as a patch request.

    protected function findImageMagick6InPaths(array $searchPaths)
    {
        $result = false;
        foreach ($searchPaths as $path) {
            if (Environment::isWindows()) {
                $executable = 'identify.exe';

                if (!@is_file($path . $executable)) {
                    $executable = 'magick.exe';
                }
            } else {
                $executable = 'identify';
            }

            if(@is_readable($path)) {
                    $binaryPath = $path . $executable;
                    if (!file_exists($binaryPath) || !is_executable($binaryPath)) {
                        continue;
                    }

                    $command = escapeshellarg($binaryPath) . ' -version';
                    $executingResult = [];
                    CommandUtility::exec($command, $executingResult);
                    // First line of exec command should contain string GraphicsMagick
                    $firstResultLine = array_shift($executingResult);
                    // Example: "Version: ImageMagick 6.6.0-4 2012-05-02 Q16 http://www.imagemagick.org" 
                    if (is_string($firstResultLine) && str_contains($firstResultLine, 'ImageMagick')) {
                        [, $version] = explode('ImageMagick', $firstResultLine);
                        // Example: "6.6.0-4" 
                        [$version] = explode(' ', trim($version));
                        if (version_compare($version, '6.0.0') >= 0) {
                            $this->foundPath = $path;
                            $result = true;
                            break;
                        }
                    }
            }
        }
        return $result;
    }
