 * I fixed it! I am sorry I should have turned off all of the plugins before posting.
   The fix was turning off – JetPack Boost > Defer Non-Essential JavaScript.

 * Hi,
 * I was getting the same error even with the official Twenty Twenty theme. The 
   solution is to install the latest Gutenberg plugin.
    Regards.
