Right after finishing lvl 23 I got an error message. Tried to pass the lvl i think 6 times and still the same error message has appeared. There I attached the crash report.

Your Crashlog wrote:GZDoom version 1.7.1 (r1526) / ZDoom 2.6.1 (r4129) (Feb 10 2013)

Try grabbing a newer copy of GZDoom to see if the problem persists.

Official release version

FWiW, the crashlog says that you were on map24 when the crash happened. So that would seem to imply that the problem is not related to map23 but something present when map24 starts.

It crashes outside any known DLL, which means it's impossible to determine the cause of the problem. Sorry.
