Defender noticed this massive file-creation spike, assumed it was ransomware behavior, and temporarily locked the temp folder to run a quick scan. That half-second lock caused a total file-lock collision, and the installation failed. , a freeware compression utility, is a powerful

If your hard drive hits a bad sector while writing the unpacked chunk, the algorithm panics.
