Hey @Matthias Schlimm, sorry I missed this from a couple of months ago, but this is what happens when the path to the executable and command line arguments combined are greater than 203 characters for a published application. It starts a new session and logs off immediately, but will launch okay if there is an existing session. So if you cannot reduce this length, you need to use a batch file or PowerShell script instead. It's been a bug/limitation for years.
