We’re in crunch so this is urgent. Can anyone help please?

Hi Antidamage,

Did you upgrade your project from 4.16.1? Do you see this same thing happen in a new test project?

Hi Antidamage,

We have not heard back from you for a while. Do you still need help with this issue? I will be marking this post as resolved for internal tracking purposes, but please feel free to add a comment and re-open the post if you need any additional assistance.

Sorry, forgot I had left the ticket open.

Attempting to upgrade again worked. It seems like failures during project version upgrades are common as this has happened a few times before on different projects.

I am glad to hear that your project is working again. There is always a of something going wrong when upgrading a project to a new Engine version, which is why we always recommend upgrading a copy of the project to make sure the original is still available.
