This problem did come along recently. You can check the top few search results in this search: Search results for '#software:ide-2-x micronucleus' - Arduino Forum

There is one that has a solution mark: 2.2.1 board manager, download additional boards - #28 by ptillisch so it will be your best bet :wink:
