At least from what I noticed on my end.
One thing I noticed since this update when tabbed out the game tab on task bar glows orange like a traffic indicator. I understand the purpose of it but it seems kinda something that should be optional?
Its mentioned in the patch notes.
The Elder Scrolls Online taskbar icon on PC clients will now light up if something time sensitive (ready checks, combat, etc.) occurs in-game when it’s not being focused.
I noticed the crashes when I do have seems to be when I'm tabbed out and not focused on the game. Otherwise I've not seen it being much of an issue with me only when it comes to that traffic signal like blinker. As I do pretty log in sometimes only to be kicked out to long in screen after so long if I get distracted with something like say making and posting threads on the forums example. If I feel like browsing I might just browse the web that signal thing goes off and at some point a crash screen pops up. So I think it is the traffic blinker being the main cause of the crashes for many players facing them right now. I just got that intuition about that one. As many of the times I've crashed that was happening and that blinker was going off. There might be a couple of times I crashed without it going off but majority of them happen with it going off.
Edit: For those that don't understand what I'm talking about or what a task bar is this is the task bar. Everyone on pc should know it.

Eso icon when its running will be shown on the task bar as do all pc applications that are open. When the game is active now blinks like a traffic signal. To alert people to things going on in the game if they are using say google chrome or doing other tasks outside the game. I think its the biggest source of the crashes going on right now.
