mapSelect error crashing editor

I have the plugin in use in two unpublished sites, that both are multisite installs and WordPress 5.5.1.

When editing pages editor crashes down at least when adding a reusable block to page and trying to edit that.

Can be reproduced with TwentyTwenty theme and Block Pattern Builder is only active plugin.

react-dom.min.js:103 Error: An error occurred while running 'mapSelect': Cannot read property 'name' of null
The error may be correlated with this previous error:
TypeError: Cannot read property 'name' of null
