Describe your issue

libmamba doesn't expect condarc option experimental: [jlap] (list of strings to enable experimental flags)

Prints many error libmamba Bad conversion of configurable 'experimental' from source '~/.condarc' : yaml-cpp: error at line 15, column 15: bad conversion

Instead, it should allow this field without complaint.
