post-update hook fail on Windows 11 and mathlib 4.18 +, "error: input/output error (error code: 5)"

[tribbloid]

this problem can only be observed on Windows, Linux can update the library successfully

attempted to fix with AI, here is everything that has been tried:

Let me check if there are any Lake-related files in the current directory and show the current status before running the update.
ls lake-manifest.json lakefile.lean
lakefile.lean  lake-manifest.json
Great, I can see the Lake project files are present. I'll now run the Lake update command which will update the project's dependencies according to the manifest.
lake update

info: toolchain not updated; already up-to-date
info: mathlib: running post-update hooks
error: input/output error (error code: 5)
It seems there was an I/O error while trying to update the Lake dependencies. The error occurred specifically during the mathlib post-update hooks. Let's try to fix this by:

1. First cleaning any potentially corrupted state
2. Then attempting the update again

I'll run a lake clean first.
lake clean
The clean completed successfully. Now let's try the update again, this time with the --verbose flag to get more information if there's another error.

The verbose output shows that the error is consistently happening during mathlib's post-update hooks. Since we're on Windows (as indicated by the path separators), this could be related to file system permissions or locked files. Let's try to:

1. First ensure we're not in a git operation by checking git status
2. Then try to remove the mathlib package directory completely and let Lake re-fetch it

We're still getting the same I/O error during mathlib's post-update hooks, even with a fresh clone. This persistent error might be related to:
1. File system permissions
2. Anti-virus software interference
3. Locked files or processes

Let's try to:
1. First check if we have write permissions in the .lake directory
2. Then try running Lake with administrator privileges using 'Run as Administrator'

First, let's check our permissions:
The permissions look correct - we have read and write access to the .lake directory. Since we're still encountering I/O errors and we're on Windows, we should try to run the Lake update with elevated privileges. 

Unfortunately, I cannot directly execute commands with elevated privileges through the terminal. I recommend you try the following steps manually:

1. Open a new terminal/PowerShell as Administrator
2. Navigate to your project directory: cd /d/peng/git/__MATH/lp2-lc-lean4
3. Run lake update in that elevated terminal

If that doesn't work, you might also want to:
1. Check if any antivirus software is blocking operations in the .lake directory
2. Try temporarily disabling Windows Defender real-time protection
3. Ensure there are no locked files by closing any IDEs or editors that might be accessing the project
