Unreal Engine 5 C++: Section 3-44. Compiling a C++ Project

Unreal Courses Ask
#1

When I compile by selecting ‘ObstacleAssualtEditor Win64 Development Build’ in VSCode, an error occurs as attached below, and when I open the project in Unreal, an error message appears as attached.
I tried downgrading the version of VSCode and putting it in the drive where the Unreal Engine files are, but the project does not open at all. What should I do?
Current VSCode version: 1.96.4
Current VS version: 2022 (17.12.4)
Current UE version: 5.4.4
And I am using .Net 6.0

Here’s how I solved it:

  1. Open Visual Studio Installer and search for “MSVC x64 14.38” in [Modify] → [Individual Components].
  2. Select Build Tools and install it.

In Compiling issue. UE5.3 - #2 by DanM, I added the following code, which caused a new error, so I modified it and then reverted it back to the original, and the execution was completed successfully. * Running task in folder UE_5.4: Engine\Build\BatchFiles\Build.bat ObstacleAssaultEditor Win64 Development ‘E:\Unreal Projects\ObstacleAssault\ObstacleAssault.uproject’ -waitmutex
