What platform?
I'm on PC NA and I've had 0 issues or crashes.
PC-NA, as well, and I've not had any crashes personally, though I've been in groups where people have crashed during the Undaunted event. During a vSO HM run last Friday, the healer logging our run crashed during the 0% poison bomb phase on the Serpent. It's funny to watch the replay on esologs and see it end suddenly before the encounter is actually over. lol

Same here; 0 crashes on PC NA and PC EU. But I've run only normal dungeons, and only the first variation of a dungeon, so it may just be that I've successfully avoided running any dungeons with liches in them.
I haven't had 0 crashes, but I haven't had many. There were crashes in Fang Lair constantly leading up to the event. I haven't tried that dungeon since the event started.
I’m on the PC NA server and during this event I’ve only had one instance of severe desync / lag in a dungeon and usually no one crashes / dcs — at most one person in group does once and so it is no great trouble to wait for them to log back on. Of course I would like crashes and lag to be even rarer, but in my experience it has not been intolerable, nor much worse than other MMORPGs.
I consistently crash on first boss in scalecaller and enterering a door in Wgt. Wierdly enough I was the one player not crashing at lich bosses throughout whole event(2-3 group members did every time).
Veit ég aðég hékk vindga meiði á nætr allar níu, geiri undaðr og gefinn Oðni, sjálfr sjálfum mér, á þeim meiði er manngi veit hvers hann af rótum rennr.
PC EU, running 2-3 normal dungeons each evening (skipping DLC sometimes), duo, zero crashes. My second half, who I run with, crashed around three times, once on Caluurion, other two probably on lich bosses too (neither of us remember exactly).
