I'm also running into this on Windows with version 3.1.2. Here is a stack trace:

In Process.php line 350:

[Symfony\Component\Process\Exception\RuntimeException]
Unable to launch a new process.

$process = new Process([$this->plantUmlBinaryPath, '-tsvg', $pumlFileLocation], DIR, null, null, 600.0);

The failing symfony process code starting at line 350 in process.php:

    $this->process = @proc_open($commandline, $descriptors, $this->processPipes->pipes, $this->cwd, $envPairs, $this->options);

    if (!\is_resource($this->process)) {
        throw new RuntimeException('Unable to launch a new process.');
    }

Seems to be Windows specific. Some search results indicate that using the following should resolve the issue:

$process->setEnhanceWindowsCompatibility(false);
