1. Does it happen for any share target?
2. Does the target app received data before the app crash?

[unixasket]

1. Maybe: I tested: Signal Messenger, Filemanager+ (for storing a ICS file local), Telegram Messenger, Fairemail all crashes.
2. Sometimes, its different: Fairemail become no data, Threema Messenger become the data and send an ics file correct. Signal sometimes, filemanager+ become no data

Does it happen to all events?

[unixasket]

Oh, ok, no, others work! The event is saved in my nextcloud (synced with DAVx5) and it has 2 invitations. Maybe the invitations are the reason? Other events in the same calendar works (without invitations).
