Bug 2019.3 APIUpdater failes if username contains whitespace

I'm trying to upgrade my project from 2019.2 to 2019.3. However, the APIUpdater drops the following error message four times:
Unhandled Exception:
System.IO.DirectoryNotFoundException: Could not find a part of the path "$pathToUnityProject\$LastPartOfUsernameAfterWhitespaceCharacter\AppData\Local\Temp\tmp3f9769a6.tmp".

Let's say your OS username is "Max Mustermann", making the directory to your %LocalAppData% variable look like this:
C:\Users\Max Mustermann\AppData\Local

In my case, the APIUpdater is expecting my LocalAppData temp directory to be in
D:\Projects\NameOfMyUnityProject\Mustermann\AppData\Local\Temp

This, of course, is doomed to fail. I think this should definitely fixed before releasing the 2018.3!

Can reproduce!

 

Yeah, I could workaround this issue by creating a new user account on my OS with the username "asdf". Upgrading the same project from that account worked. Lol

 

Thx for that, I was thinking about that too !

This is great, can't wait for the fix as this issue has held up a project I updated recently some scripts are misbehaving, must be a regression as my user directory never changed

 

Which 2020.1 version is this fix arriving in? It still exists in 2020.1.0a16

 

Thanks for fixing. Will it also be included in the next 2019 releases?
