Slow errors with Enfold keep crashing our site. :/ Debug inside

Hi everyone! Since launching primarycolormusic.com we’ve had the site go down for many hours on two separate occasions. On both occasions our host was kind enough to provide an error log to try and trace the culprit and both times it has been a slew of slow_errors from Enfold. Here’s a log:

Our host is managed hosting from getflywheel.com so it’ s not slouchy hosting. Any idea how we can fix this?
