APIUpdater Fails on build constantly on any new projects

I have made a fresh install of the 2020.1 Alpha 2020.1.0a14 and it constantly gives me errors about the API Updater, especially on build it completely stops builds from happening in fresh projects even with an empty scene!

What it seems to be doing is mixing the project directory with the C Drive AppData/Local/Temp folder for some reason like the project directory string and local temp appdata strings are being merged together? It is likely the space between Rob and Farthing in the User location is causing this.

I have submitted a bug report at case 1201864 on fogbugz

The error I get is:

Error building Player: APIUpdater encountered some issues and was not able to finish.


    Unhandled Exception:
    System.IO.DirectoryNotFoundException: Could not find a part of the path "D:\Unity Projects\SRPMain\SRP_Main\Farthing\AppData\Local\Temp\tmp61e69b83.tmp".

The correct location of the Temp file is C:\Users\Rob Farthing\AppData\Local\Temp

This issue seems to exist in 2019.3 as well:

Rather odd I don’t have the issue in any of my 2019.3 projects

No mention of a fix in alpha 16 :'(
