[Bug] Fresh PyPi Installation (0.4.0) panics (?) during optimization without logs or errors

[CodingTil]

Steps to reproduce

1. Install PyGCGOpt (preferably in a fresh environment):

pip install pygcgopt
# or
uv add pygcgopt

2. Try to optimize anything. See https://github.com/CodingTil/gcg-minimal-example for a reproductive example.

Expected behaviour

The optimization process starts, we see the calculation logs, etc.

Actual behaviour

The program immediately panics (?) without any error / exception or log being printed, and terminates with exit code 139.
Also see the Action https://github.com/CodingTil/gcg-minimal-example/actions/runs/16841312086 that confirms the issue is not just local on my machine.

Just ran across https://scipopt.github.io/PyGCGOpt/INSTALL.html
If I manually re-install pyscipopt==5.2.1, then it works.

IMO, dependencies should be pinned to the exact version. (This has cost me 2 hours)
