Description of the bug

conda create --name nf-core python=3.12 nf-core=3.4.1
Channels:
 - conda-forge
 - bioconda
Platform: linux-64
Collecting package metadata (repodata.json): done
Solving environment: failed

LibMambaUnsatisfiableError: Encountered problems while solving:
  - nothing provides _python_rc needed by python-3.14.0rc1-h4dad89b_2_cp314t

Could not solve for environment specs
The following packages are incompatible
├─ nf-core =3.4.1 * is installable and it requires
│  └─ python >=3.13 * with the potential options
│     ├─ python [3.13.0|3.13.1|...|3.14.0], which can be installed;
│     └─ python [3.14.0rc1|3.14.0rc2|3.14.0rc3] would require
│        └─ _python_rc =* *, which does not exist (perhaps a missing channel);
└─ python =3.12 * is not installable because it conflicts with any installable versions previously reported.
