incredibuild build source ue4 4.26

Good time of day. When using incredibuild, it throws this error

C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\MSBuild\Microsoft\VC\v160\Microsoft.MakeFile.Targets(45,5): error MSB3073: The command "..\..\Build\BatchFiles\Build.bat-Target= "UE4Editor Win64 Development" - Target= "ShaderCompileWorker Win64 Development-Quiet" - WaitMutex -FromMsBuild " exited with code 6.

don’t tell me what to do? the search on the forum did not give any results.

at the first start, just the Build software did not want to work, even after switching to the VS Community geometry. It only worked when the entire project was rebuilt
