actually, i did not know that the script for linux. Thats right, i am trying to run this script on windows machine (on the same machine that hosted otrs system)because OTRS need OTRS Daemon. But is there any solution or tool may be help to let this code to run on windows server 2012 r2? Thanks

Hmmm ... I don't have any experience with Windows' Linux Subsystem, and that exception code (Ausnahmecode) c0000005 is a more or less general "Access denied".

I suppose OTRS is running from that subsystem. Do you run the script from a shell in that same subsystem, or from a CMD.EXE prompt? And is the user running the script the same user that OTRS service or daemon is running?

i run this script from cmd.exe . and from windows powershell but the same error. Actually i had always one problem that it asked me, you could not run this script as root you should run it as otrs user. i created user called otrs on windows then i tried to run the script but still always give me this error. So i delete the code (loop if) that it is responsible about checking if the user is root or otrs user. because i did not understand where i should create this user. The user in database is otrs. I don know if you have idea also about this problem. Thanks in advance
