Sporadic build failures in 5.8.1 in CI related to UBA / Detour

We’re seeing sporadic build failures in CI with messages like this:

UbaSessionServer - Unknown message type 208 when communicating with detoured process UnrealEditor-AndroidTargetPlatform.dll (Link [x64]) (4461). (Message index 61 after 9.8s)

For now we’re going to disable Detour by default, but it would be nice to keep (we don’t currently have a build farm for UBA/remote, but we still see reasonable gains on full local rebuilds with it enabled). Anyone aware of a fix for this? Thank you

Hi there, sorry for the late answer.

My recommendation is to take latest binaries from main and try them. UBA is designed to always be backward compatible (with one exception which was changing osx to be case sensitive a year ago or so)

If you still get this issue, then we will need to work together to figure out why this is happening. I have never seen a report like this.

Thanks,

Henrik
