I encounter the same problem as you with the latest patch, the crash occurs always of a StackHash error.

The StackHash error occurs when DEP is invoked and has an issue with whatever application you’re trying to run ,
the error is related to Data Execution Prevention.
If DEP notices a program on your computer using memory incorrectly, it closes the program and notifies you. It is as such a security feature.

I tried to disable DEP for iClone6 but unfortunately Windows 10 does not allows to disable DEP for 64bit programs.

Looks like you found it. We have similar systems - same update. Sounds like a problem for Reallusion to solve. Interestingly, certain project seem stable, others not. Has something to do with the type of props that are loaded. Seems the planes (two dimensional props) are culprits. I unload the planes and the system becomes more stable. It's a hypothesis. I've sent the errant project to RL. Let's see what they find. Good luck.

Since I applied the update, the characters I imported from 3dxchange will no longer lipsynch to an audio file. It was working before.

the marketplace downloader is giving me the same issue with the fresh install also.  At the moment,  i am completely locked out of the market place because of the current downloader.

Most of my pre 6.4 projects crash within seconds of opening. It doesn't matter how large or small, or what options are set. I've tried both Directx 9 and 11 modes. New projects are fine.

I have this same issue and my new projects also fail after a while. Tried numerous reinstalls and hardware updates, etc.

The issue i am having is this:

When i double click any of the content files (motions, props etc), iclone freezes for 3-4 secs and then it unfreezes and loads the file, but it also resets the folder from which i took the content, and it goes back to the first one. So for example, if i open the folders: "Props/3d Props/Wall and Floor/Wall," and  i double click  to open the wall, all the previous folders that i opened on the left side close and return to the Props folder... Weirdly, when i use drag-and-drop, this issue doesn't occur. Still, it is a bit annoying, and it didn't happen in pre 6.4...

Also, is it my idea or 6.4 loads weirdly the pre 6.4 projects? I experience crashes and a lot of jitter/lag...

I'm having the same crash issue with new and old projects. I have done everything from resetting my computer of 8 months to factory settings and starting all over loading only Reallusion products. I even tried the install with Windows 8.1 before upgrading to Windows 10 but to no avail. I have nVidia GTX860 (latest upgrade), Directx 12, and 1TB of HD with 16GB RAM. I ran the dxdiag and all checks out fine. I have reached out to the tech department (just last night) and expect to hear from them soon but I wanted to post here for others to see I'm having the same issues. Thanks Reallusion. You are appreciated.

I can confirm that new projects are also crashing. The frequency of crashes with new projects is lessened if I reboot the PC, but merely closing and reopening iClone doesn't help.

I just want to report that I do not have any problems right now. So, crashing projects are not caused by the update only ...
