From shapely 2.0 release notes:

Multi-part geometries such as MultiPolygon no longer behave as “sequences”. This means that they no longer have a length, are not iterable, and are not indexable anymore. Use the .geoms attribute instead to access individual parts of a multi-part geometry.

Second issue: GeoAxes.outline_patch was deprecated in this PR: https://github.com/SciTools/cartopy/pull/1213

can be fixed by: GeoAxes.spines['geo']
