"Checking storage" after application update

I recently received a Bangle.JS v.1 (software version 2v10.103).

1. I connected my smartwatch to https://banglejs.com/apps/#
   
2. Moved to the "My Applications" section
   
3. There was a proposal to update the application. I did it.
   Now, at startup, it shows "Checking storage" and the case does not progress further.
   If I try to install the default applications through the tab "About", then I get an error "App Install failed, Not all apps found, missing boot,launch,mclock,setting,about,alarm,widbat,widbt,welcome".
   
   

How to fix it?
