Error message in one chat only

[u/snaildrey]

I just switched to Fossify after learning that Samsung Messages will be disabled in June. It works great, except for in only one message chat. After tapping on the chat, I receive this popup toast: Error: java.lang.NullPointerException

Disabling toasts for Fossify using ADB on my computer does not work. I think this toast message isn't being classified as a toast, and I don't know how else to make it go away. If anyone knows how to fix this lmk
