    Here are some similar issues that might help you. Please check if they can solve your problem.

    Possible solution (Extracted from existing issue, might be incorrect; please verify carefully)

    Solution 1:

    Perform a clean installation of Azure CLI:

    1. Go to Control Panel > Uninstall a program, uninstall Microsoft Azure CLI.
    2. Delete C:\Program Files\Microsoft SDKs\Azure\CLI2 (for x64) or C:\Program Files (x86)\Microsoft SDKs\Azure\CLI2 (for x86).
    3. Reinstall Azure CLI from scratch using the MSI installer.

    This resolves the issue by ensuring no conflicting files remain from previous installations.

    Reference:

    Solution 2:

    Repair the Azure CLI installation by reinstalling the required Python package:

    Open an administrator command prompt and run:

    "C:\Program Files\Microsoft SDKs\Azure\CLI2\python.exe" -m pip install pywin32==311 --force-reinstall

    This fixes the issue by repairing the PyWin32 dependency.

    Reference:

    Solution 3:

    Uninstall and reinstall Azure CLI using winget:

    1. Uninstall Azure CLI:
    winget uninstall --id Microsoft.AzureCLI -e
    1. Delete the contents of C:\Program Files\Microsoft SDKs\Azure\CLI2 if not automatically removed.
    2. Reinstall Azure CLI:
    winget install --id Microsoft.AzureCLI -e -s winget

    This ensures a clean installation and resolves the issue.
