White Screen when posting or editing

When trying to edit or add new content on WordPress, the entire screen “loads” as white. No sidebar or admin bar. 100% white screen. Otherwise, the site works as expected.

I’ve tried the following:

– Updating wordpress version (wordpress 5.7)
– Removing all plugins
– Switching to original (twenty nineteen) theme
– Switching browser type (chrome / opera)
– Tried different php versions.
– Tried modsec on/off
– Ran security/server health scan (wordfence security plug in) which came back normal

None of this has worked. The error that shows up under dev console is:

JQMIGRATE: Migrate is installed, version 3.3.2

I’ve had this “blank page” issue since wordpress 5.X.X (not sure exactly which version). I thought updating wordpress would solve the issue. I’m now running 5.7 and still have the issue.

Any hints ?
