AI edits storage fails to read, write, or update

Hey, I just found this when searching the internet and it worked for me!  FINALLY!!!  Hope it helps you too😀

The Fast Fix: Purge the Corrupted Cache

You can force Lightroom to build a fresh, uncorrupted data container. [1]

1. Completely close Lightroom Classic.
2. Navigate to the folder on your hard drive where your Lightroom Catalog is stored. (If you aren't sure where it is, check the default Pictures / Lightroom folder or look up the location via the Adobe Help Guide on Catalog Paths).
3. Look for a file or folder named [YourCatalogName].lrcat-data.
4. Move this file out of the folder and onto your desktop (as a temporary safety backup).
5. Relaunch Lightroom Classic. [1, 2, 3, 5]

Lightroom will automatically generate a clean, brand-new .lrcat-data file. The annoying popup window should disappear, and you can test a normal backup upon closing the program. [1, 2, 3, 4]

I am having this exact same issue.  I have tried everything on my end including create a new catalog and transfer to it.  Still no luck on fixing the issue and I’m now also not able to back up my catalog no matter what drive I try to back it up on since the latest update

Lightroom Classic stores AI masks and other AI data in 'Catalogname.lrcat-data'. Sometimes this file (Mac)/folder (Windows) gets corrupted, or the permissions are getting set wrongly, so Lightroom Classic cannot write to it. That explains what you are seeing. Take the following steps:

1: Review this document: https://helpx.adobe.com/lightroom-classic/kb/ai-edits-storage-error.html to make sure you are not affected by the items listed there. 
2: Contact Adobe Support as they have an lrcat-data recovery tool that can fix your corrupt file. Contact Adobe Customer Care at https://helpx.adobe.com/contact/what-contact-options.html.
