I assume it's related to rich presence / colored terminal prints?

Hey thanks for reporting!
We will try reproducing this issue.
I think a major cause is also that we don't have good testing on windows @KRRT7

Thanks for the report, the issue here is with python and windows, specifically inside GHA windows runners, nothing to do with rich or codeflash.

The CI agent, for all OSes, actually executes the commands and redirects the output to a file, on windows, this results in the encoding being set to cp1252 which causes this error in the cp1252 encoder python uses, you can see more information here
setting the python IO encoding type i.e

env:
  PYTHONIOENCODING: "utf8"

should clear this error up for you
