Whenever I try to share a video in a text channel, the whole app crashes

Whenever I try to share a meme onto a channel of a server, it seems like it'll work for a second, and then promptly crashes. I tried multiple times, forcing the app to close, and even clearing the cache. No dice. (Android, Version 209.14 - Stable, I also submitted the debug log in the app settings)

Others seem to be complaining about the new design, but this is a feature that doesn't seem to have changed compared to before the redesign and it's broken. That may be unrelated, but there's a definite correlation based solely on timing.
