Yes I was referring to launching the build as a standalone application (either via the editor or from Visual Studio using the “DebugGame” configuration).
I wrote down the steps after I reproduced it with one of the default template projects. That’s why I forgot listing the step about building the Development Version for cooking to succeed.
I will try to reproduce it on my laptop tomorrow and see if I can reproduce it there too. If it helps I could also provide you with the project I was using last and a minidump from when the issue occurred.
To avoid the issue I have already switched my main project back to 4.8.3. However I hope the issue can be resolved before 4.9 stable goes live or I’ll have to hold back on updating until it’s fixed.
