TTS initialization error on a FAW (Full Android Watch)

[MrCsabaToth]

The Watch is a LEMFO LEMP Android 9 watch. When the app starts and the various native sections get initialized, the TTS emits an error:

The message is kind of telling "Commonly this is caused by using a wear build on a phone or vice versa.". This is not a Wear OS on a phone, but the question is what is the 'vice versa' case. Because this is a full Android on a Watch and that use-case might fit that.

Another same error:

Note, that the Speech Recognition & Synthesis package is installed on the watch by default (https://www.apkmirror.com/apk/google-inc/google-text-to-speech-engine/)

[MrCsabaToth]

I installed Android Accessibility Suite and Voice Access apps from Google LLC

Then tried to discover any place where language can be configured, such as:

• Settings > Google Services & preferences > Settings for Google apps > Search, Assistant & Voice

• Voice (voice, offline speech recognition) > Other settings > Language, autocomplete, autoplay

• Settings > System (Languages, time) > ...

Then I restarted and the exception doesn't come now. The question is of the service will work. It might be that somehow I was able to install a TTS engine with any of those two apps, however even before that I saw both input and output sides and English was there at least for each direction! We'll see.
