Version

• python : 3.10.13.final.0
• OS : Linux
• OS-release : 5.15.0-79-generic
• CVXPY Version: 1.41

Additional context
I created a new docker image with mamba / conda-forge and the new build fails, same build was running last week without any issues. Not sure which dependency drives this issue.

[SteveDiamond]

The issue is with the latest pyscipopt release (interface to SCIP, not part of cvxpy)

[MMCMA]

I don't see any recent releases in SCIP - do I miss something?

[MMCMA]

I can confirm, setting the SCIP version to 8.0.4 fixes the problem
