Hmm, it does say 5.3 is supported on the plugin page, but I thought it should be 5.4 (two versions back) - https://wordpress.org/plugins/gutenberg/

Oh, 5.5 is two versions back, oops. I confirmed on slack that this should be the minimum supported version (https://wordpress.slack.com/archives/C02QB2JS7/p1614856290064700). The plugin page is wrong for some reason.

@3dflip Apologies for that. I'd recommend either downgrading your Gutenberg plugin, or upgrading your WordPress installation.
