I deleted those files and the problem still occurred.
What’s more I have tried recreating the project in a completely new file/folder and have just experienced the same crash.
A quick search about “failed to create directories” suggests that the program unreal engine should be saved on the same drive that the project is being saved onto, which mine is not. Is this a possible cause for the issue, or am i mistaken with something else?
Thank you for you help though!
