I got this error when I release it to test flight and test on my mac M4:

I do build with entitlements: flet build macos --info-plist LSApplicationCategoryType="public.app-category.productivity" --macos-entitlements com.apple.security.app-sandbox=True --build-number $(date +%y%m%d%H%M)

[FeodorFitsner]

OK, as it's sandbox my guess would be #2 from here: " it could be a problem with signing 3rd-party python packages (like pydantic) unpacked during the first run."

Will investigate.

I got another one, it is : .cpython-312-darwin.so' not valid for use in process: library load disallowed by system policy. It also relates to numpy. I tried this solution(flet-dev/serious-python#85 (comment)), but did not work.

ImportError:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

• The Python version is: Python3.12 from "/Applications/diogenesaibutlerflet.app/Contents/MacOS/diogenesaibutlerflet"
• The NumPy version is: "1.26.4"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
