==================================================================================================================================================================================== We are using StartSpeakingText(src_text) API and we dont use future in our code, still the stack shows crash at __future_base

Please let us know what more details you require from us

Hi @gauravG2021 @pankopon , I think we fixed this bug and delivered a private drop to @gauravG2021. And release 1.19 will contain this fix. Thanks.
