MacOS – Xcrun missing, installing Xcode Command Line Tools not fixing issue

high sierrahomebrewmacosxcode

I have a Mid 2015 MacBook Pro running macOS High Sierra 10.13.3.

I tried starting up a new project and none of my commands seem to work.

I always get this error:

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), 
missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

Seems pretty straight forward, Xcode Command Line Tools missing. Except installing it seems to not work/have no effect.

I enter: xcode-select --install, press install, agree to the agreement, it downloads, installs, gives me a nice The software was installed but if I try any command again (like brew update or brew upgrade); I get the same error. (I tried rebooting, but to no effect).

How do I resolve this issue? All I could find on Google is people saying Install Xcode Command Line Tools.

Okay, After a full day of attempts, re-installing homebrew and all... found a solution which I should have tried a lot earlier in all honesty. Leaving it here if anyone else has the same problem in the future:

Doing xcode-select --install showed everything as being installed correctly but I just couldn't confirm that anywhere. I downloaded the CLT as a pkg from the apple developer website (https://developer.apple.com/download/more/) and installed it the old fashioned way. CLT is now installed and homebrew is detecting it just fine.

Brew Config now:
