WebIDE All Existing SAPUI5 Apps failing Build

Since 03/10/2019 all of my previously working SAPUI5 Projects are now failing to build:

9:50:02 AM (DIBuild) [INFO] Retrieving source code

[ERROR] An unexpected error has occurred during the build

[INFO] Build finished in 0 seconds

There is no log, nothing in the Dist Folder (It's always empty), in the chrome console:

{"message":"dist/di.code-validation.core_issues.json does not exist or is not a file"}

Is this a service wide issue? One of my colleagues on another Subaccount is also expereicning the same issue.
