Source build trying to open launcher built project

Development Platform & Builds

I finally managed to get unreal 5.2.1 to build, and I understood that if I build with the same release tag as the launcher build, I should be able to open projects built with the launcher build and go back and forth between launcher and source engine builds, but when I try to open a 5.2.1 unreal project file with my source built 5.2.1 engine, it wants me to convert the project , did I do something wrong here

the project is using launcher-downloaded unreal 5.2.1, and I downloaded 5.2.1 release from github, built it with no modifications, all of the plugins are inside of the project’s plugin folder not the engine, why can’t I now open the project with both the launcher 5.2.1 and my source built 5.2.1 ? thanks

also if i click “skip conversion” a “missing modules” window comes up listing the project itself, and the code plugins that are in the project’s plugins folder

Hi Timi,

I think ‘asset versioning’ is based on ChangeList number.

Hover over the project name in the upper-right of the screen to see. (5.2.1 is 26001984)

If you open assets in a later/higher CL you can’t open again in a lower.

So the first step would be making sure those numbers are the same.

The fact you need two installation of the same engine version to work in a project is beyond my understanding.
Your source build will be newer than the one in the Epic Launcher.
You have to be more specific on what you trying to accomplish going back and forth between versions.
