Could it be the new version crashes on the Watch Apps page, if there are apps installed which are not available in the store (anymore)? I had an own old experiment installed, and the app Transmission ({5a3de317-b050-4140-aa37-c85f19c446eb}), both are not in the store. When I manually removed them from the apps.conf, and from the directory, things went back to normal. I can see updates for other apps, and search the store etc.

[Edit]
Other than that, thanks or the update. I can finally manage the tokens in the Authenticator app
