Issue Git deployment - stop application pool

I've setup a github repository that pushes deployment files to a "deploy" branch.
This github repository has an ASP.NET Core web application.
I've configured a git-hook to notify Plesk for push-events.

Plesk then automatically tries to clone the files into the application root,
but the application pool is still running, which means that the DLL is locked.

gitmng failed: error: unable to unlink old 'CICD.dll': Invalid argument (Error code 1)

When I suspend the application pool, and trigger a deployment, everything works as expected.
But I have to do so manually.

How can I make sure that Plesk suspends the application pool with git-deployment?

touch app_offline.htm

seems to release the lock on the dll.
But is it possible to have a pre-deploy action and post-deploy action?

Deploy actions:

touch tmp/restart.txt

Currently I have the following post-deploy actions:

echo "" > app_offline.htm
DEL /F /Q *.exe *.dll *.pdb
copy publish . /y
DEL /Q app_offline.htm
DEL /Q publish

The COPY is being executed successfully, but all subsequent commands aren't executed anymore.
What could be causing this?
