CLion 2020.3 - Visual Studio Build Tools link error

I have recently encountered an issue where I get loads of errors when CMake does a basic compiler check.

The errors are as follows:

"C:\Program Files\JetBrains\CLion 2020.3.2\bin\cmake\win\bin\cmake.exe" -DCMAKE_BUILD_TYPE=Debug "-DCMAKE_C_COMPILER=C:/Program Files/LLVM/bin/clang-cl.exe" "-DCMAKE_CXX_COMPILER=C:/Program Files/LLVM/bin/clang-cl.exe" -DCMAKE_C_FLAGS=-m64 -DCMAKE_CXX_FLAGS=-m64 -G "CodeBlocks - NMake Makefiles" D:\ASGE-Repositories\asgenetgame-team-11

CMake Error at C:/Program Files/JetBrains/CLion 2020.3.2/bin/cmake/win/share/cmake-3.17/Modules/CMakeTestCXXCompiler.cmake:53 (message):
  The C++ compiler

    "C:/Program Files/LLVM/bin/clang-cl.exe"

  is not able to compile a simple test program.

  It fails with the following output:

I have tried reinstalling both CLion & Visual studio build tools, as well as installing different versions of both, but neither has done anything to change the error messages.

Below is my toolchain setup as well
