I'm in AI 2022 Version 26.0. I've also tried 26.0.1 (only other available older version in the CC Desktop App). My files do not open anymore at all. Even when opening the app without any file it just looks like this.
I've also searched similar experiences here, & I unfortunately cannot go as far as doing solutions that involve changing something in the Mac system as this is a company laptop. I am using Macbook Pro 2020, i5 1.4GHZ Intel, 8GB Memory.
Hope this resolves soon as I can't get work done and extremely frustrating.
