This was a test build, and the results were as follows.
There were no errors in the files themselves.
In fact, since everything worked fine until now, I believe the possibility of a file error is extremely low.

At the moment, I can't replicate this. But I have a theory that (assuming that you are on R5) there may be some path handling errors. An update to R6 brought a rework on how relative paths are constructed (so the encryption can work properly, regardless of OS). It is a possibility that the affected files end up on the wrong path (judging from the file not found error in the dev console).
