Crashes for me too, same app version.
I'm wondering if this app is still being developed? Maybe I've just lost track of time, but it feels like a long time since there's been any updates, and I'm on the beta branch.
I'm grateful for its existence at all, it's the best Lemmy client by far, but Lemmy is adding new features over time and such, and I wonder if Boost's development is proceeding behind the scenes or not...
