This has happened to me in various CC programs, but Ilustrator is the one most persistent. Basically I have Illustrator open most of the day and am switching between various apps in my workflow. Most commonly, when I return to Illustrator after it has been open for a while the CC library panel will be frozen. I am unable to click on anything in there, and if I resize the panel it distorts the contents. Sometimes the panel is partially frozen and I find out by trying to apply a color swatch, but instead the click opens a graphic asset that is no where near where I selected on the screen.

The only fix is to quit the program and relaunch it. Occasionally, it happens during the time I am working in the program, but mostly I find it that way after returning to it. This is getting so disruptive that I am finding myself avoiding use of the libraries panel altogether. This says a lot because this is normally one of the most cohesive and convenient parts of my workflow.

I have read various posts on this, I am familiar with and at times relaunch Creative Cloud. However, none of these actions make a lasting change. I recently updated to a new Mac Studio and I had hoped that this issue was somehow tied to the fusion drive on my old computer. Unfortunately, I am experiencing the same issues on this new system. There is something wrong with CC libraries that has been causing this issue for at least a year and persists with the most recent updates. This needs to be fixed.
