Hi! I am getting a problem on my website using latest BB version on Wordpress 5.7.2.
I am unable to modify any block on any page. Click on the block, but nothing happens.
Any idea on why this is happening?
First step is to test for a plugin conflict:

Other possible causes are a JS error or your theme loading the CDN or another version of jQuery aside from the version loaded with WP.
I have tried to disable all plugins except BB, but no results…I am not using a CDN, so that should not been the issue.
My bet is a JS or jQuery error but don’t know how to check that 
The srange thing is that a similar website with same plugins, on same hosting seems to work fine…
I would suggest that you submit a ticket in that case:
