conda with libmamba solver does not work in offline mode

What happened?
We have an environment without connection to the internet with a shared Conda Python installation. Regular Python users do not have write access to the installation. They use conda create ... to create their Conda environments. With the classic solver it works fine. But with the libmamba solver it does not work.
For the example below I created a small environment to reproduce the bug.
It's easy to reproduce. You only need a read only Conda installation.

An unexpected error has occurred. Conda has prepared the above report.
If you suspect this error is being caused by a malfunctioning plugin,
consider using the --no-plugins option to turn off plugins.
Example: conda --no-plugins install <package>
Alternatively, you can set the CONDA_NO_PLUGINS environment variable on
the command line to run the command without plugins enabled.
Example: CONDA_NO_PLUGINS=true conda install <package>
If submitted, this report will be used by core maintainers to improve
future releases of conda.
Would you like conda to send this report to the core maintainers? [y/N]: N
