Summary

Running a Python cBot on linux/arm64 platform using the image tag : 5.10.1 crashes before the algo starts:

Environment

• Any Python-language cBot (backtest or run)

The same algo and command work fine on image 5.9.11.

Root cause

The bundled Python is linked against OpenSSL 1.1, but 5.10.1 dropped the libssl1.1 runtime libraries from the image:

Image variant	_ssl.cpython-312-*.so needs	Ships	Result
5.9.11 arm64	libssl.so.1.1, libcrypto.so.1.1	libssl.so.1.1, libcrypto.so.1.1	works
5.10.1 arm64	libssl.so.1.1, libcrypto.so.1.1	only libssl.so.3, libcrypto.so.3	broken
