windows 10 projected file system issues

[HHWRyan]

I am trying to virtualize our c++ unreal engine 5 project, including the UE5 engine source, so it is a gigantic project.

The project compiles and runs with no issue, I can run the editor, work on assets, and submit like normal.

The only issue I am having now is with Entrian code search. Entrian doesnt work at all in PrjFS environment, some initial debugging tells me for whatever reason PrjFS's get file data callback, when triggered by Entrian(ess.exe, invoked by the VS instance of my UE project) is always stuck in PrjWriteFileData, the function call will never return, unless I intentionally close my Visual Studio.

This feels like a projFS bug to me, or if not, any insights?
Btw I am working in c++, with PrjFS api on windows 10.

Thanks a lot!
