Hi.

I tried to upgrade ELK 8.14.3 to 8.15.0  
Ubuntu version 22.04

Using the following command:  
sudo apt-get update && sudo apt-get upgrade

I got this error message on frontend:

```auto
[I18n] A `formats` must be a non-empty object.

Version: 8.15.0
Build: 76360
Error: [I18n] A `formats` must be a non-empty object.

```

Note: all datastream and indices deleted before upgrade so there is no any data in elasticsearch.

Before upgrade everything works well. I had to roll back.

Last time I rolled back to a previous state, version 8.14.3.  
Today I ran an update then restarted the server and ELK started with version 8.15.0.  
I don't know what happened, I did everything like last time when I got an error.
