Can't build with IL2CPP on both Windows and Android

I get 3 errors in the console:

for the first error I get this:

Win32Exception: ApplicationName='C:\Program Files\Unity\2019.4.0f1\Editor\Data\il2cpp/build/deploy/net471/il2cpp.exe', CommandLine='--convert-to-cpp --emit-null-checks --enable-array-bounds-check --dotnetprofile="unityaot" --compile-cpp --libil2cpp-static --platform="WindowsDesktop" --architecture="x64" --configuration="Release" --outputpath="C:\Users\ishan\Desktop\CodeJamProject\Temp/StagingArea/Data\Native\GameAssembly.dll" --cachedirectory="C:\Users\ishan\Desktop\CodeJamProject\Assets..\Library/il2cpp_cache" --profiler-report --map-file-parser="C:/Program Files/Unity/2019.4.0f1/Editor/Data/Tools/MapFileParser/MapFileParser.exe" --directory=C:/Users/ishan/Desktop/CodeJamProject/Temp/StagingArea/Data/Managed --generatedcppdir=C:/Users/ishan/Desktop/CodeJamProject/Temp/StagingArea/Data/il2cppOutput ', CurrentDirectory='C:\Users\ishan\Desktop\CodeJamProject\Temp\StagingArea\Data\Managed', Native error= The requested operation requires elevation.

and for the third I get this:

any help would be greatly appreciated
