Installed Anaconda3-2024.10-1-Windows-x86\_64 .

conda 24.11.3

Anaconda-Navigator does not launch

1. Tried Uninstalling / Installing several time
2. Tried running conda update, navigator update from command prompt. None seems to work.
3. Also disabled AntiVirus just in case. Still no affect.

Following is the error when trying to launch from the command prompt
