It may be caused by Xdebug. If you’re not using it, see this specific post I made on how to disable it: Speed Issues on Local Machine. Or, you can increase the nesting limit by adjusting (or adding) xdebug.max_nesting_level to the php.ini file and setting it to a high value like 500.
Also, you can switch to the Preferred environment which doesn’t have Xdebug by exporting the site and then re-importing it.
