An unexpected error has occurred. Conda has prepared the above report.

試したこと

始めはanacondaで同様のエラーが出力されました。
アンインストール後に再インストールをしても変わらないため，現在はminicondaでテストをしています。

心当たりは最近CUDAをインストールしたことです。
そのためCUDA関連のソフトを全てアンインストールしましたが，エラーコードの中に以下の文がありCUDAを認識しているようです。
virtual packages : __cuda=11.2=0

また環境構築以外，例えば
conda install pandas
でも同様のエラーコードが出力されます。

補足情報（FW/ツールのバージョンなど）

以下のバージョンで試しました。エラーコードは同様です。
Miniconda3：Conda 4.10.3 Python 3.9.5
Conda 4.10.3 Python 3.8.10

Comments

[ppaul]

conda create -n
は、-n の後に仮想環境名が必要です。
conda create -n mypython
だとどうなりますか？

[trifle]

すみません。コマンドが抜けていました。

エラーコードに`$ C:\Users\71529862\Miniconda3\Scripts\conda-script.py create -n test`
とあるように仮想環境名をtestで指定して実行しています。

Answer 1

.condarcを削除したところ上記エラーが消えました。
