Field not found: EmberAPI.Master.eLang

[gits68]

Hi,
Operating system : Windows 10 22H2
Visual Studio : Community 2015 Version 14.0.25420 Update 3
fresh build from commit ca53632 (HEAD -> master, origin/master, origin/HEAD)
needed to replace NuGet w/ a fresh one => NuGet Version: 6.3.1.1
Launch EMM, goto Edit->Settings, then the following popup appear and EMM crash : Field not found: EmberAPI.Master.eLang
any idea ?

I think that's because i pushed just a part of the new code to GitHub. Unfortunately I'm still not able to do the rest of the (big) changes atm.
