Error on Apple Silicon when installing ComfyUI with 2.10.3

When I try to install the ComfyUI package the application closes and the error is the following:

Fatal Python error: init_import_site: Failed to import the site module

An addendum, it looks like this is only happening when using an ExFAT volume for the data

[tanis2000]

Some more info... it looks like this was an issue with venv and the filest that macOS creates to store the metadata on volumes that do not natively support them. All those files start with "._" and the error you see is that 0xb0 character which is actually the dot character.

It migth have been fixed in one of the Python 3.10.xx versions because I have been able to use venv on that volume with 3.10.14.

I am going to try to replace the one distributed with StabilityMatrix with a copy of my 3.10.14 and see if that makes any difference

It seems this was a CPython bug python/cpython#114145 that was fixed first in the 3.10.14 release, we'll look into an update on our end.

yes, that really looks like it. Thanks for looking it up
