Hi,
I have huge problems to upgrade many of my projects from 4.15/4.16 to 4.17.1. The Unreal Engine crashes during the startup phase.
It seems to be a bug in the current version because this is reproducible. For safety I tested also to upgrade my 4.15 projects to 4.16.The conversion works without any problems.
Can you fix this in the next updates?
Best regards, Andreas
Try to start your project from VS, probably there is an error in your project’s code (maybe some deprecated function call).
Thank you very much for your help. But unfortunately I don’t know how I can open a project with Visual Studio…
Try to delete ./Binaries, ./Build, ./Intermediate and ./Saved folders in your project.
Before you switch, delete the Intermediate folder, and then try upgrade.
I tried to delete these folders. But the Unreal Engine 4 crashes again. I started also a debugging. I get this output in Visual Studio. But unfortunately I don´t know what I have to do with this information…
I migrated the whole content from my 4.16 project to a blank 4.17 project. This is at the moment the only solution. I don´t know why it is not possible to upgrade 4.15/4.16 projects to 4.17… I never had this problem in the past…
