The CScalp application can consume a large amount of resources on your PC and run unstable because of incorrect operation of Visual C++ program components. To avoid this you should check:
1. How many versions of the Visual C++ component are installed on the computer.
2. If there are multiple versions you should delete everything.
3. Install one current Visual C++ component (2015-2019 versions).
Then check your PC resources and stability of CScalp.
You can download Visual C++ components on Microsoft's official website
