In 9.1.104.1 we get regular crashes (me and the other OTT on the project; we haven’t transitioned MTTs to 9 yet, waiting for better stability and line-break issues to be resolved).
The crashes increase markedly when we’re using Zoom’s screen share function. (One of us OTTs is in-country, the other in the States, and we regularly have team meetings to review material in Paratext via Zoom.) In a single morning of work in PT 9.1 via Zoom with screen sharing, we’ll often have 3 crashes, about one an hour. Normal work in PT 9.1 (no Zoom) yields only about 1 crash a day, sometimes none.
I’ll try to start looking at Event Viewer when it happens, and if I get anything in the log, I’ll pass it on via Give Feedback in PT.
