Access violation error while running wireless simulation in omnet++ 6

Question

I have created LTE network(ned file and ini file) using simu 5G. Everything was fine but when I run simulation error shown as below.Please help

Exception code=0xc0000005 flags=0x0 at 0x00007FFACAC121DB. Access violation - attempting to read data at address 0x0000000000000000

i was trying to run simulation to collect LTE data.

To determine what part of code generates this exception, you may set in omnetpp.ini:

debug-on-error = true

Then build the project in debug mode, and start debugging it. Debugger will stop just before the line which occurs an error.
