When performing a complete uninstall of my anaconda installation (update via interface didn’t work) and re-install using Anaconda3-2024.06-1-Windows-x86_64.exe (SHA256:45EEF9132B70E3D5A493C26429DDB4E2C9278A32097FD4BC729F860685633A3B) , I get the error below when doing something simple like conda install -c conda-forge mamba
ERROR conda.core.link:_execute(950): An error occurred while installing package ‘conda-forge::fmt-10.2.1-h181d51b_0’.

[Errno 2] No such file or directory: 'F:\\Users\\luc\\ana3\\conda-meta\\conda-24.5.0-py312haa95532_0.json'
I tried many things such as setting the environment variable to utf-8, but that didn’t help.
PYTHONIOENCODING=utf-8
PYTHONUTF8=1
The only thing that worked so far is again uninstalling everything, deleting the .conda and .anaconda folder in my user folder (C:\Users<username>) and starting from an older version of the anaconda installation file (Anaconda3-2024.02-1-Windows-x86_64.exe; SHA256: 087C633E355BC709222AD9E0DBAD77ABEED84F7E06DBDBECAE84BA8B3660429E) and perform the upgrades via the GUI to the latest version.
Did other people experience this, what causes this and how was it solved?
Thanks for your feedback,
