Hi i have the same issue, it worked again when I systematically deactivated other plugins in troubleshooting but only worked for 1 edit on each plug in, then wont load again, its stuck with the logo flashing. I tried increasing my memory in config.php file. if i deactivate the below plug ins in troubleshooting mode it works but not when i disable troubleshoot:
yoast seo
contact form 7
wp-supercache
wordfence
minimal coming soon & maintenance mode
