Hi Andy,
As if now we are aware of the issues wherein customers are having difficulties in updating Creative Cloud Desktop app. error P205 is one of the known and reported errors as of now
P213 seems to be quite similar to this as this is also an app update error
Our engineering team is already working on this and it should be fixed very soon
In the meantime, you can try reinstalling the Desktop app from the below link:
