Unity 2020.1.0f1 HDRP not building at all? ilcpp.exe did not run properly?

I have created a project with the above Unity version and the HDRP preset. I Instantly build it without changing a single thing in the entire project, but it failed to build. Then I deleted everything and just created a scene with only a camera. That didnt build either. The error messages were exactly the same. Something is wrong with ilcpp.exe.
Does anybody know what exactly that means/ how I can fix it?

Oh. Im trying to build x64 for windows with all default settigns btw. Forgot to mention.
