Yep. Submitted a bug report the first few times it happened. I have just reverted back to Ipswich. Will see how it goes. Thanks for the advice.

Yep. Submitted a bug report the first few times it happened. I have just reverted back to Ipswich. Will see how it goes. Thanks for the advice.

Now that I recall, when it crashed the Fault Reporter box came up and I got to explain in detail just what I was doing when the crash happened. I even got email notification of it. I like this Fault Reporter. It's a very efficient way of reporting a bug. Hopefully we'll see a hotfix soon.

I'm not getting the fault reporter. Perhaps I'm impatient? For me, the screen goes gray and the app accepts no input. I'm not hugely patient. I might wait a minute or two but not hours for it to resolve. Then I kill the app and re-launch.
 
There is never anything in the minidumps folder.
%appdata%\Cakewalk\SONAR Platinum\MiniDumps\Plugins
 
I know that one of the freeze cases was related to TH3 because TH3 fixed it. This made me assume that other cases were also related to TH3, but I'm not so sure.

But wait, I just checked the Windows Application Log and I'm finding lots of this...
 
I right clicked "My Computer/This PC" Icon > Manage > Comp Management > Event Viewer > Windows Logs > Application then filtered for errors and warnings.

I get a crash when recording midi in lexington update, as soon as I hit space bar to stop midi rec, sonar crashes :( , haven't tried audio rec yet...

IN my case with Lexington, I didn't have to wait, in fact the first thing that happened is the Fault Report screen popped up, before it shut down Plat. I answered the questions, filled in the details of how it happened and hit "send" to send the info to Cakewalk. Then it said it will now close sonar.
 
I've actually had lots of crashes with Platinum since June when I got my new studiocat computer and Win 8.1 Pro. I'm still trying to figure out the causes, although recently I've found that Komplete 9 is causing crashing in certain situations. All of these Komplete crashes were total computer freezes where I had to reboot the computer and I didn't get any DMP files.
 
I went to Windows logs and did what you did, but none of my crashes are showing up, I guess because they were complete freezes, where the computer can't even make an error log. Did you have to set something up differently to get those errors logs to show Sonar crashes?  I see in your situation Fault Reporter is even crashing at times.

I didn't have to set anything up. It just occurred to me to check the application log.

Lots of instability here as well, no 32 bit anything, but frequent freezing, usually when hitting spacebar to start or stop, or even clicking in FX areas to open a plugin, even if the plugin is disabled. Looks like I'll be taking a walk back a version for the time being.

Have you had many crashes before Lexington? I've had more crashes than I think I should over the months, but Lexington was worse for sure.

I'm glad I found this thread. I'm also having the same, or at least a similar problem with SONAR Platinum x64 Lexington.  The three conditions mentioned at the top of this post are the same (take lanes on, sound on sound mode, existing data in the previous take lanes).  I was recording a MIDI track, and I reproduced it a total of four times (and never saw a situation with these conditions in which it did not occur) in the course of trying to see if there was some plugin conflict involved.  I record as short or long as I like, hit the space bar to stop recording, and boom!  In my case, SONAR's Fault Reporter dialog never comes up, just a normal Windows application crash, and the Event Viewer shows a heap corruption crash in ntdll.dll.  (Despite pointing to an operating system library, heap corruption crashes are usually bugs in applications in managing their dynamically allocated memory.)  I'll paste the event information at the bottom of this post.
 
I initially thought it might be something relating to using my Akai EWI USB since today was the first time I plugged it in since upgrading to Windows 10, but trying that with a simpler project and a fresh track did not have the same issue.  (Interestingly, though, trying to remove the EWI plugin from that simple project, without deleting the associated track, hung.  However, then trying again with the same plugin I'd been using in my original project, Arturia's AnalogLab, didn't have an issue removing the track in the simpler project.) I've also verified that, if I turn the take lanes off, there is no crash on stopping recording, so I'm going to guess that the issue comes in allocating memory to hold the new take lane (which makes me wonder if the crash will just end up being delayed to when I show take lanes again later).  In any event, there does at least seem to be a workaround at this point (i.e. just turn take lanes off while recording).
