The game crashes and the packcheck doesn't work

I started updating when launching the game using the client, and after the update was completed, it crashed when I clicked to load. When I tried to start the game again, the system froze and I had to restart my computer. Upon restarting the client, it indicated that it was corrupted and prompted me to use packcheck, but packcheck informed me that the game files were corrupted and could only be re-downloaded. Since yesterday, this has been the case with every update, and I have re-downloaded it three times already. I hope you can optimize the update process to avoid damaging the entire installation package; downloading a 94GB file is really challenging.
