The inline traceback narrows this to a read from the already-open input .nup (self.f.read(...) in Nup.copy_to), after roughly 4.8 GiB had been extracted. It is not a traceback from opening the destination file. The output drive's reported free space therefore does not explain this particular error. This does not establish corruption, an antivirus cause, or a Longshot extraction bug.

To distinguish the remaining causes, could you add metadata only: whether the input .nup is on a local disk, removable/network storage or a cloud-synced folder; that input volume's file system; whether the failures already observed stop at the same point; and any matching Windows disk or protection event? Please omit private paths and do not upload the .nup or extracted game files. No elevation or protection changes are needed for this diagnosis.

Triage: S0 install/build blocker; one reporter, confidence 0.4 under the workflow, affected reach unmeasured. No patch or cause is claimed yet. Current main still passes unrelated PermissionError through; changing that into a retry would not establish why this read was denied.
