Just updated to 4.16.2. Our project will no longer load due to a garbage collection related access violation exception.

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.
