Matrix Games Forums

Each time when I try to start this scenario it instantly crashes when clicking enter scenario in the briefing screen and it is only for this scenario, I have tried doing a clean install of the whole game and specifically deleting the scenario and then verifying files in Steam to ensure that nothing is wrong with the file but it still instantly crashes. I have attached the logs I found only thing I could see is the "Function:ScenEdit_RunScript (0) Error:File path 'DeveloperMode.lua' not found" when I try to open it in the editor but it also crashes when trying to open it normally.

Does anybody have any idea why it does not work?

Hi, please give us a bit of time to be able to look into that. Thanks!

Not very helpful, but a datapoint...It works fine on my machine under 1825.11. Win11, Ultra 9 285HX, 5090. Log had no issues in it.

In the meantime you may investigate in the event viewer after one of those crashes, perhaps it will help to solve the problem.

Not able to repro the crash here. As Nikel said, can you provide any errors that occurr in the Event Viewer window, on application tab?

Thank you

I had some extra time now and was troubleshooting it on the new beta and I still hade these crashes on both this scenario and some others, I never got any errors in the notebook but then one time loaded in and then when I tried again it crashed and i got these errors messages in the log. When I asked an AI about it said the it was that I was missing some windows codecs, WebP Image Extension, and HEIF Image Extension and when i installed these it works now without crashes.
