Very suddenly (like I mean a half hour later with nothing else changing), Stream Links no longer work on Android/Google TV. At first, it was just my CCWGTV on 3.5.2 and it was working on my TS4K+ on 3.5.1, but I updated the app and the OS (looks like it was stuck in the past due to space issues) and now it is having the same problem. Instead of opening an app (or attempting to open one it cannot), it is trying to play the file with Playback Failed (-17).
Also, just to be sure, I updated to pre-release 2021.07.23.1501, rebooted everything, all that jazz. It made no difference. I then attempted on my Android Phone and got the same issue. There does not seem to be a problem in the web, so it looks like something is not talking from the Google side.

EDIT: It seems to be specific to TV Shows and Movies that it groups as an "episode". Other movies appear to be launching. I have tested the same with Netflix, Hulu, Disney+, Kanopy, and Hoopla.
