Did you get anywhere with this? I am having the same issue.
I solved the problem by removing the local OS account in the policy.
On another server I had the same error although I didn't specify an OS account.
This happened because JDK version 11 was installed on the server. This version is probably not supported by the Patrol Agent yet, because JRE doesn't have its own folder structure anymore and is fully integrated into JDK.
I hope I was able to help you.
