hi,  
I’ve been using anaconda virtual environment properly for a long time, and  
recently I got error to create new environment after I reinstall anaconda.  
The error message is like as follows. Can you help me? Thanks.

An unexpected error has occurred. Conda has prepared the above report.  
If you suspect this error is being caused by a malfunctioning plugin,  
consider using the --no-plugins option to turn off plugins.

Example: conda --no-plugins install

Alternatively, you can set the CONDA\_NO\_PLUGINS environment variable on  
the command line to run the command without plugins enabled.

Example: CONDA\_NO\_PLUGINS=true conda install

If submitted, this report will be used by core maintainers to improve  
future releases of conda.  
Would you like conda to send this report to the core maintainers? [y/N]: y  
Upload did not complete.

Thank you for helping to improve conda.  
Opt-in to always sending reports (and not see this message again)  
by running

```
$ conda config --set report_errors true

The error you’re encountering is related to a compatibility issue between the architecture of the libraries on your system and your processor architecture. Specifically, the `libcrypto.3.dylib` library, which is required by the `libmamba` library, is built for the `x86_64` architecture, while your MacBook Pro is running on an ARM-based chip (`arm64e` or `arm64`), which is typical for Apple Silicon Macs (M1, M2, etc.).

Steps to take:

**Ensure you’re using the correct Miniforge installer:**

- If you’re using an Apple Silicon (M1, M2) Mac, make sure you have installed the correct version of Miniforge for ARM architecture (`arm64`).
- You can download the appropriate version [here](https://github.com/conda-forge/miniforge).
- Uninstall miniforge `rm -rf ~/miniforge3`
- Then, reinstall Miniforge with the correct architecture and create the environment

Thank you for the help. I reinstalled the miniforge and actually, I forgot to source the miniforge/bin/activate file. Thanks a lot!
