When using the AssemblyInfo Updater, i get:
Failed to update 'C:\BuildAgent\Ws\1512'. Access to the path 'C:\BuildAgent\Ws\1512' is denied.
AssemblyInfo update action failed
I've enabled the property logging previously and it appears before the error. Also the file is always updated correctly.
I have no idea whats the updater is trying to do additionally with the root path of the build. which is causing this error.

hm, ok. i’ve recreated the whole action, now it works. maybe the action editor has some bugs.
