I can confirm the language/string problem. I’m using a German WordPress installation and right after the ACF PRO update almost all strings are broken.
Awesome! Thanks a lot, Elliot.
There is another topic in this forum regarding the same problem. This is what I posted there:
Okay, here’s a quick workaround until the bug has been resolved:
In the admin panel where the field groups and fields are defined, you have to set the preview image of each image field to “thumbnail”. After that, the upload/selection of an image won’t fail anymore. Except the uploaded image is even smaller than 150×150 pixels (the standard size of the WordPress thumbnails).
As long as it’s larger than that, you’re fine.
It’s not a real fix, though, and I hope the bug will be resolved soon.

I can confirm this bug. I just updated to 5.0.8 and can’t use the image field anymore (neither on options pages nor anywhere else). Console gives me this:
Uncaught Error: A "url" property or function must be specified
Edit:
Did some further testing and found out that only images <=1024 pixels width are affected. If I upload an image that’s 1025 (or more) pixels wide, it works.
Maybe that helps.
