Any luck? I am about to attempt this as well.

I happen to resolve my Media Uploader issue with some CSS added via admin_head — after testing via a few different WP “Single Site” cases on my VPS to fix an issue on a clients WP Multisite.
• This code fixes the “Media Uploader’s” content visibility.
• This fixed the issue when tested on separate installs and cases for WordPress 5.9 – 6 “Gutenberg Blocks” and Advanced Custom Fields Pro “Blocks” 5.10 – 5.12.2.
Here a snapshot:

Now I may proceed with using ACF Blocks and Inner Blocks!!!
I have been persistent on fixing my issue for the past few days and I hope this helps someone.
Any solution to this yet? I am on WordPress 5.9.1 (Multisite) with ACF Pro 5.12.2.
I tried the code from https://support.advancedcustomfields.com/forums/topic/update-to-wp-5-9-1-breaks-media-selection/#post-152581 and it did not work.
From what all I read thus far, it seems to the only solution is to role WordPress back to 5.9? Any quick help would be appreciated.
My media selection modal appears.. however content area is blank in the “Upload files” and “Media Library” tabs.
