2020-12 is not a supported release. I just spent several days working on a pull request to fix some of the issues, with the one you listed here being the worst. It relies extensively on an internal API that changed. I'm not sure 2020-3 really works either, for different reasons, though there too the plugin will install. I ended up going back to Eclipse 2019-11.
