Can you please provide us with your project.It will help us in recreating the issue.
Sure can. Sorry about not attaching it before, but thought maybe somebody else had seen this issue so there might be a quick fix. This is an archive made directly from the repository. I just verified that it displays this issue. (i.e. first clean and build fails because one of the generated files contains a whole bunch of null characters, while a second clean and build works properly). I have multiple workspaces that display this issue, but this is the simplest one.
To try and figure out what is going on, I uninstalled Creator 3.2 and
Creator 4.1 update 1. My computer is windows 7 with .NET Framework 4.7
installed. I then re-installed Creator 4.1 update 1. Opened the project
and did a clean and build, and saw the same issue as before.
Hopefully the added info will help you reproduce the issue.
