从错误信息来看，问题在于UnicodeDecodeError: 'gbk' codec can't decode byte 0x90 in position 93: illegal multibyte sequence。这表明你的env.yaml文件可能包含了某些非标准的编码字符，而conda在读取这个文件时使用了GBK编码进行解码，但遇到了无法识别的字节序列。

解决这个问题有几种方法，你可以尝试以下步骤之一：

方法一：转换文件编码

将env.yaml文件的编码转换为UTF-8，因为UTF-8是通用的编码方式，可以兼容更多的字符集。你可以使用文本编辑器（如Notepad++、VSCode等）打开文件，并将其另存为UTF-8编码。

方法二：手动修改文件

打开env.yaml文件，检查第93个位置附近的字符，看看是否有特殊字符或乱码，尝试删除或替换这些字符，确保文件内容只包含标准的ASCII字符或常见的Unicode字符。

方法三：使用命令行工具转换文件编码

如果你熟悉命令行操作，可以使用以下命令来转换文件编码：

powershell -Command "(Get-Content env.yaml -Encoding Byte) | % { [Text.Encoding]::UTF8.GetString($_) } | Set-Content env.yaml -Encoding UTF8"

这条命令会读取env.yaml文件的字节流，然后使用UTF-8编码重新写入文件，从而转换文件编码。

方法四：创建新的环境

如果上述方法都无法解决问题，或者你不想修改现有的env.yaml文件，可以尝试创建一个全新的环境，然后手动添加你需要的包。这可以通过以下命令完成：

conda create --name new_env_name python=3.x
conda activate new_env_name
conda install package1 package2 ... # 替换package1, package2...为你需要的包名

选择适合你情况的方法进行操作，通常情况下，转换文件编码到UTF-8是最直接有效的解决方案。如果还有其他疑问，欢迎继续提问。
