We updated to cordova-android 10.1.1 yesterday. It has a number of changes - see this blog post for more information.

Not all plugins have been updated for Cordova 10 yet. If you find problems with a plugin, check with the maintainer whether it should work, and open an issue there if needed. In the meantime, you can drop back to Cordova 9 - but that is not a permanent solution.
