Subtitle issue with Infuse 6 Pro

I know that Infuse 6 Pro has stopped receiving updates, but it has been working fine for me. Recently, after an automatic system update on Apple TV, ASS subtitles in Chinese are not displaying correctly. Could you please help me resolve this issue? Thank you for your assistance!

This is related to changes/bugs in Apple’s new software (iOS/tvOS 18 and macOS 15).

Apple may include fixes for this issue in a future update or you may consider upgrading to Infuse 7.
