Anyone else seeing this?

Are you using a combination of VST3 (any) followed by a UAD plug?
 
That is a known bug and Noel stated last night he has a solution.

Same here.

What is the content of these projects?  What/How many effects? Driver modes? 

I am working on a project from X2 and so far it has been a major crash fest;  I am guaranteed to crash at some point during my session without fail.  I am now thinking I should have stuck with X2 since I can't use X3 in its current form.
 
I get crashes almost every time with UAD, but I am not sure (since I am not near my computer at the moment) if my UAD crashes are related to the VST 3 / 2 thing as mentioned by Noel and above.

I know we are working with UA to fix this issue.

The UAD crash has been reproduced successfully and we are aware of it. Can you confirm that it's happening in the same manner as this post?

I don't have any UAD stuff and am still experiencing crashes.

Hi James-

Also if you have crashes make sure you submit crash dumps and list the CWBRN numbers so we can identify your report.
