5.2.1 update seems to break Gutenberg

[glorious1]

ABT Version: 5.2.1

PHP Version: 7.3.9

Theme: GeneratePress, also tried Twenty Nineteen

Plugin List: Tried with only ABT active

Browser: Firefox 69.0.1

Expected behavior: Gutenberg works

Actual behavior: When I go to edit a page with block editor, I get "The editor has encountered an unexpected error"

Classic editor still works. Using Health Check plugin, with all plugins off and 2019 theme, block editor works. Activating only ABT breaks it.
