Cannot open HandsTrainSample because Engine modules are out of date.
I wanted to try out Hand Tracking with UE4, and I just did git clone the engine source from Oculus github, and build the engine following the instruction in the Oculus website. I cloned 1e09d2f (the latest one) from branch 4.25, which is release "oculus-4.25.3-release-1.51.0-v19.0" and built the engine using Visual Studio 2019.
It worked fine, I could make a new project. I could also open HandSample project and it works great with Oculus Quest & Link. But I couldn't open HandsTrainSample.
I built the engine and clicked Debug/Start a new instance in Visual Studio, then it opened up the editor. Then I chose the sample, but I couldn't open it. I also tried to open .uproject directly but it just says "The following modules are missing or build with a different engine version: HandsTrainSample Would you like to rebuild them now?" and if i go Yes, then I get Missing Modules error with the message "Engine modules are out of date, and cannot be compiled while the engine is running. Please build through your IDE." and I couldn't open it.
I guess I have to find and fix errors in VS but I don't even know where I can get .sln file for this project so which I need to see errors in VS. I tried Generate Visual Studio project files from HandsTrainSample.uproject but .sln file wasn't generated in the same directory although I got no error.
This is my first time to build the engine from source and I might misunderstand some stuff. I hope someone helps me with it.

Log file closed, 08/08/20 11:35:33 Thanks for your solution. I can open the project and deploy to my Quest 2 but the sample show nothing. It just playing some sound with a whole black view.
Thank you for following up on this. I had the same error. In my case, I had also downloaded just the SharedSpaces example project in a zip file in addition to the oculus fork source engine. I was getting build errors when I tried to rebuild the SharedSpaces solution. I realized I needed to right click on the SharedSpaces uproject file and set the source engine version as the associated engine, not the launcher version.
