GSoc 2024 BRL and FreeCAD integration

hello while building my project.
I got an error message.

"Severity	Code	Description	Project	File	Line	Suppression State	Details
Error	NETSDK1013	The TargetFramework value '' was not recognized. It may be misspelled. If not, then the TargetFrameworkIdentifier and/or TargetFrameworkVersion properties must be specified explicitly.	ALL_BUILD	C:\Program Files\dotnet\sdk\8.0.200\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.TargetFrameworkInference.targets	96		
"

even though I have not defined any target in build properties.

although all packages have been built and build runs all the workbenches properly.
Would it be a problem
also I had issues while building the FEM and Part modules , page file size was not enough
