Clear the Cache and Restart the Game

I cannot guarantee that this will fix Uplay has Detected an Unrecoverable Error and Must Shut down the error, but it is worth a shot. Go to the directory where you have installed the game from Ubisoft. It will usually be under the uplay directory in the parent drive.

Commonly it will be the C drive>>Program files>>Ubisoft. It may vary based on the default taken by the wizard at the first launch.

ubisoft login

Once you find a folder that will typically be named as cache, delete it and its contents. Then, restart your game and see if the problem with Uplay has been resolved. If it has not been solved yet, restart your entire PC and then try again.

Use the task manager to kill all the play-related tasks from the background context. Then restart the services again using the game shortcut you have on your desktop (hopefully).

So restarting it after closing it down may fix the errors.
