Can you check which engine are you using on both platforms?
Or try to use for example engine="openpyxl" for reading and writing on Intel and a M3.

Also check which engine(s) is actually installed on both machines.

Another idea could be to check out Pandas code from git - https://pandas.pydata.org/docs/development/contributing.html#version-control-git-and-github
(for the version you are using) and try running a test suite
there - https://pandas.pydata.org/docs/development/contributing_codebase.html#running-the-test-suite

Some tests may fail, as per documentation, but this can give some
interesting insight.

Otherwise the option of the last resort - to present a minimal reproducible
test case demonstrating your problem.
