How to start Windows process w/o terminating it?

after deployment, I start a process, but GitHub actions terminate it:

Cleaning up orphan processes
Terminate orphan process: pid (12352) (myprocess)

I would like that GitHub actions would finish without terminating myprocess (in other words, “run something in the background and continue onto other steps”).
How to do that?

Unfortunately that’s not possible. Depending on what you’re trying to accomplish, we could find an alternative. Are you trying to run a service or something and then send/receive information from it in later steps?
