Seems like our problems might be related, I dont know.

When I want to edit a block, i am in the habit of selecting the block first, then entering BE for block editor.  It then opens up the Block Editor dialogue box, with the selected block already highlighted, and all i have to do is hit enter to go into the block editor.  For some reason, the selection is not working anymore, and I have to scroll down a list a mile long to find the block name I want to edit.
