LibMambaUnsatisfiableError: Encountered problems while solving:
- nothing provides _python_rc needed by python-3.12.0rc3-rc3_h30d4d87_1_cpython
Could not solve for environment specs
The following packages are incompatible
├─ iris >=3.9.0 is installable and it requires
│ └─ python >=3.10 with the potential options
│ ├─ python [3.10.0|3.10.1|...|3.12.4], which can be installed;
│ └─ python 3.12.0rc3 would require
│ └─ _python_rc, which does not exist (perhaps a missing channel);
└─ python 3.9.*,>=3.9 is not installable because it conflicts with any installable versions previously reported.
