Bug: CC Libraries keep reinitializing
Hello, I have a problem with CC Libraries occuring in multiple applications (Photoshop, Illustrator, Premiere...).
Everything worked fine for months, but 2 days ago the Library window started to act up (I didn't fiddle with settings nor files, I don't know the reason why it broke just now).
CC Library keeps reinitializing, then shows the library content for 2 seconds, then refreshes, displays a generic error message (Something went wrong initializing Creative Cloud Libraries), then changes to message about the need to sign up to use libraries and automatically proceeds to showing the content again - and then the cycle continues.
Because of that the CC Libraries are completely unusable. (Creative Cloud application also shows that there is a problem with syncing libraries, but nothing specific)

Even when I stop synchronisation in CC App, the library keeps trying to sync and reinitialize (seems like a bug on its own), completely ignoring my attempt to stay offline.
I also use the same account on another computer (both Windows) and there's no problem at all on the other device.
So far I've tried what had been suggested in these topics:

https://community.adobe.com/t5/Illustrator/CC-Library-panel-content-flashing-on-and-off/td-p/8905489
To sum up: I tried relaunching all CC apps (while pausing and restarting file syncing), I cleaned cache by deleting whole CCLibrary directory, I killed all Adobe related processes and tried to manually restart CCLibrary app, I reinstalled Creative Cloud app, I used a CC Cleaner to remove CC Library and then manually reinstalled it. Nothing helped me.
I'm afraid I've run out of ideas. Do you have any advice?
