Facebook Pixel v2.01 Cannot find wp-async-task.php

Hi there. For some reason over the past night or two, the pixel plugin has caused the site to 500.

The error is below and reinstalling the plugin doesn’t help:
Warning: include(DIR\httpdocs\wp-content\plugins\official-facebook-pixel\vendor\composer/../techcrunch/wp-async-task/wp-async-task.php): failed to open stream: No such file or directory in DIR\httpdocs\wp-content\plugins\wordfence\vendor\composer\ClassLoader.php on line 444

Any help would be appreciated.

Thanks,
