We also need to investigate why the ErrorActivity is not launched. This prevents us. from getting bug reports

I am unable to reproduce it on my side on the latest nightly. Are you sure you are on the latest one?
TobiGr commentedon Dec 1, 2025
0.28.0-1079-202511300127 is the latest version, built on 2025/11/30. It happened on the main page. For whatever reason I am also unable to reproduce it now.
