The background here is:
ExecStartPre= is for preparation of the environment of the following
ExecStart=. But that cannot include any background processes.

As soon as the main process of ExecStartPre= exit()s, all things that
the main process has possibly started in the background will be
forcefully killed by systemd. The entire cgroup where ExecStartPre=
runs in will be cleaned up.

Maybe your stuff is killed before it can even really start?
ExecStartPre= cannot be used to start _any_ processes.

If that is required for your tools, the things from ExecStartPre=
should move into its own additional service file, and that one pulled
in by the main service.
