Solutions

1. Retry the build; the parameter file copy is transient in most cases.
2. Check the IDE log for the underlying I/O cause and ensure the build system directory is writable.

Example fix

Invalidate Caches / Restart, then run the build again.

When it happens

Trigger: BuildManager fails to copy a command-line parameter file into the build process working directory.

Common situations: Disk full, permission denial, or an antivirus lock while writing build parameter files.
