   I am unable to install Xcode 26.1:

   sudo env PATH=$PATH xcodes install 26.1
   
   (1/6) Found existing archive that will be used for installation at /Users/me/Library/Application Support/com.robotsandpencils.xcodes/Xcode-26.1.0+17B55.xip.
   (2/6) Unarchiving Xcode (This can take a while)
   Using regular unxip. Try passing `--experimental-unxip` for a faster unxip process
   The archive "Xcode-26.1.0+17B55.xip" is damaged and can't be expanded.
   Removing damaged XIP and re-attempting installation.

   Environment Info

   • Apple M1 Max
   • MacOS 15.7.2
   • xcodes installed through homebrew
   • I have to use sudo due to security measures on my device that I can't do anything about. It hasn't caused any issues in the past.
   • Up until now, the xcodes install command has worked perfectly for me (past 3-ish years).
