Edit More Details shows white screen

[rielyncampbell]

On gutenberg sites with or without gutenberg plugin activated, when opening a media file through the media library and clicking the "edit more details" link, it loads a white/blank page with the following error when inspecting the console for errors:
Uncaught (in promise) TypeError: Cannot read property 'raw' of undefined

Our classic WordPress sites function. When reverting from WP core 5.7.1 to 5.6.2, the edit more details page loads.

Tested on Macs in Chrome, safari, firefox and on PC in IE and chrome with the same results.

Additional testing narrows it down to the twenty twenty theme and not the WP update. The error appears on all other gutenberg sites in our multisite network - even those that do not have the twenty twenty theme installed or activated.
