Hi! Sorry you’re having issues. I don’t know if Pants runs on miniconda, or at least it’s not how it’s usually run… Can you try with a vanilla CPython (e.g., one installed by pyenv)?
Not sure that’s related to this error, but want to rule it out
Oh, also, what does 
file /Users/anoopmishra/.cache/pants/setup/bootstrap-Darwin-arm64/2.13.0_py39/lib/python3.9/site-packages/psutil/_psutil_osx.cpython-39-darwin.so
show?
For context: psutil doesn’t publish macos arm64 wheels, so when the venv is created during setup, the sdist will be downloaded and built.
Looks like that is being built as an x86_64 binary, even on your arm64 system, which can happen if something is running under rosetta
So my guess is that your miniconda3 interpreter is an x86_64 binary, running under rosetta?
Which you can check with 
file path/to/bin/python
b
surprisingly, when I ran 
file
on the 
cpython-39-darwin.so
file it's x86_64 but i never see this issue on my m1 under arm64 mode
