Microsoft Translator Provider: The request is not authorized because credentials are missing or invalid.

[AlexSkrn]

Microsoft Translator Provider 1.2.0.0 (same on version 1.1.5)
Trados Studio 2022 SR 2 version 17.2.10.19084

The plugin stops working about every 15 minutes with the error in the title. I need to open Project Settings and click OK. This seems to reset the plugin and it works for about another 15 minutes. This also affects the pre-translation of larger files during project preparation. It can only handle very small files. ChatGPT says that the problem might be here: MicrosoftTranslatorProvider/Service/MicrosoftService.cs There is no logic for refreshing the access token before it expires. And according to the Azure docs they do expire (I think it is from here: https://learn.microsoft.com/en-us/azure/ai-services/translator/reference/v3-0-reference#authenticating-with-an-access-token). I don't know if this is indeed the problem. This error affects many of my colleagues.

This is the error trace from the plugin log:
