We have what we believe is a fix for this problem. Unfortunately, we’re unable to verify this internally because we are unable to reproduce the problem at our end.
We have put out the fix on our pre-release stream, and would be very grateful if you could try it immediately, and let us know if it fixes the prompt, and if your chosen theme continues to be functional.
Please follow the DevStyle specific instructions on the following page to get the pre-release update.
