A couple weeks ago I had a similar error in a Windows PC. I deleted the CC program using Windows tools, downloaded a fresh Creative Cloud installation file and installed. I have not seen the error since.
Issues with CC have been going on for several days, on my iMac. (I started another string, here about it being 'buggy')
Did a session with Adobe on-line chat, but the issue is not yet resolved. (Only so much time in a day to spend problem-solving.)
When I sign-in to my Adobe account, through the web-access, everything on CC is fine. It is the CC desktop app that is the problem. Not getting the same error as shown in this string, but it takes forever to open the CC window, even tho' the icon is active on my tool bar. (Spinning wheel for a few minutes.) When it does open, several things are missing on both the top bar and side panel of the CC window. But the applications that I use, and the updates for the apps, seem to be fine.
I tried some of the helpx tips, including "Creative Cloud Cleaner" and "Creative Cloud installer stuck" steps, too. But that did not fix it.
Am wondering if I can remove CC from my actual system Library contents, and then go back to Reinstall CC?
Also wondering, if there may be some old versions of the Desktop CC app somewhere on my OS that I should remove, too? Computer is almost 3 years old - so may be some old CC stuff left on my OS (or migrated from my old OS?) that is interferring with writing the update(s).
Really would like to fix CC, if I can.
