Ok I copied the project and I will remove piece by piece and see what happens at startup to see if the crash can be eliminated this way.
The problem is, the crash occurs reliably only after Windows restart, presumably becaus some UNreal Buffers are rebuilt when the project is started fresh?
However, my machine has the typical windows problems after a few years meaning restart takes about 15 minutes until it becomes responsible so I can’t sit here all day and do restarts. I will do a little probing every day and see if I can make the crash go away
I will report back here in a few days, so my silence for a few days does not mean the problem is solved
Since you are still experiencing this crash could you post a copy of the project so that I can test on my end as well? The best way to do this is to upload the project to Dropbox and then send me a link to download it. If privacy is a concern you can send the link to me in a PM on the forums.
Thanks, this is a commercial project though, so I’m not so sure about sending it, although the client is only partly finished yet.
I have set up some experimental copies of the project which I use to remove parts selectively and then check the project each time I restart windows.
I have made some empirical progress though by removing calls to functions that are defined in the C++ game mode class as BlueprintImplementable and which are then implemented in the blueprint.
I have removed those functions from the blueprint and so far, the crash has not happened at startup for this project whereas in the complete project it happens more or less regularly at first startup of the day (yet not always).
I would like to test this for a few more days to see, if the crash is really gone when I remove these blueprint function bodies. If that is so, I guess the next question would be, what it is that makes this crash, but I need a number of days to be sure, that the crash really and positively does not happen at all in the modified project
Whereas the crash is reliably reproducable in the copy of my project that I made a few days ago, it seems to have disappeared in my working project. I don’t know what this is all about, but for the time being the problem has gone away.
You can close this case for now. If it reappears, I will report back
