I only have Awesome TTS (Google Cloud) installed, no other Add-Ons. From the error, it seems to be the TTS.
An error occurred. Please start Anki while holding down the shift key, which will temporarily disable the add-ons you have installed.
If the issue only occurs when add-ons are enabled, please use the Tools>Add-ons menu item to disable some add-ons and restart Anki, repeating until you discover the add-on that is causing the problem.
When you've discovered the add-on that is causing the problem, please report the issue on the add-ons section of our support site.

After setting my presets with the new version of Awesome TTS(427598962) to work with Korean (NAVER translate) I am having an error loading audio in the preview and with cards. The error message reads: "Request got text/html; charset=utf-8 content-type for the web request; wanted audio/mpeg." Thank you for all of your hard work.
