After a few days, I checked the site again, and it has seemed to corrected itself. No idea why, but now I am able to update! Yay!
Same problem here! Updates worked on the first few sites I was running maintenance on, but just came across it on a new site that was missing a license key initially.
After activating the license key it was still preventing me from updating.

Hi guys, I also created a ticket for this with ACF and it seems that they have found a fix!
within the ACF plugin look for the file:
/includes/api/api-helpers.php
comment out line 3390:
'context' => 'acf-upload'
UPDATE:
I think I’ve narrowed this down to an issue with the uploader setting of the acf_form. When set to ‘wp’, WordPress’ own media library uploader it works fine. But when set to ‘basic’ (meaning the use of a general html file input element), it will not show the image in the media gallery grid layout – even if you were logged into WordPress when submitting the form.
