Upgrading Test2::Plugin::Cover to 0.000022 fixes it. I believe that either the dependency expresses in META.json ("Test2::Plugin::Cover" : "0.000022") should be a hard-dependency, or the test should cope with older Test2::Plugin::Cover. The test still requires an older version:

use Test2::Require::Module 'Test2::Plugin::Cover' => '0.000018';
