Latest Update – causing Error in Block Editor

Hi, Firstly I love your plugin. Absolutely. I have spent the last month merrily creating block patterns for use on a Scottish healthcare websites. A brilliant tool to help non-designer end users.

However, just updated to latest .05 version, but had to reinstall .04 version. It is causing an error in block editor whenever I click on the pattern inserter.

I copied the error and here it is:

TypeError: Cannot read property 'name' of undefined

I had to blank out the web address as the site is still in development. Reverting back to previous version – all is well. Can you help?

Many Thanks
