Can't use C++17 in linux

If i put:

CppStandard = CppStandardVersion.Cpp17;

in my Project.Build.cs, I always get the error:

C++17 was disabled in PCH file but is currently enabled

Already tried every possible combination of PCHUsageMode

Fixed with https://github.com/EpicGames/UnrealEngine/commit/e4b3018fedad5999f8df9ea42b72810b9eddf713 in 4.25!

Thanks, it’s working now!!
