This applies to 14.5.0.0 and 14.6.0.0 (the latter more frequently I think)

After working on a project for a while, like a few hours, just doing normal things like making a lot of adjustments to cuts mostly, not using any advanced functionality, the program quits. It disappears entirely from the computer screen. It may be hung in the background someplace because it takes a reboot of the whole machine for LW to open again. This seems to reliably happen after working for a while.

It always happens exactly when I click with the mouse. It has always happened when clicking specifically on the play button in the right hand viewer, but today it happened when I clicked on something else in the right hand viewer. At the exact moment of such a click, instantly the whole LW window disappears (both if I've got a full screen one up on the other monitor). No warning, no preliminary slowdown, no error message to user.

This appeared in the Windows Application log:

I'm working with an i9/3.6GHz CPU on a fairly new Asus board with 32GB RAM. Windows 10 Pro version 1903 64-bit. No other foreground applications running.

It feels like some kind of RAM issue, the program trying to write to RAM actively in use by another part of the program or a driver or the OS. Or something like that. Not that I know anything about that stuff.

Maybe the log info is helpful for you to find a problem in the code? Maybe you can glean something from it that indicates a problem with my system?

Thanks

The V14.6 is a beta, so any crashes regarding that should be reported in the beta forum, where the developers can quickly spot it. Since it's currently at an early stage of beta testing, it's not a good idea to use it on actual productions.

Please attach a zip of the Lightworks error log to your next message.

I intentionally posted this here because it applies to 14.5.0.0, which I understand is the current production release.

To be clear, this error occurs reliably in version 14.5.0.0, the production release. You can see that in the content of the error log message.

Therefore, I hope and intend that developers responsible for the production release will benefit from this post.

I mentioned - parenthetically, indicating that it's less important - that it also happens in the beta 14.6.0.0 in case that information can get passed along as appropriate. I'm not going to generate the equivalent error in 14.6 and make a largely identical post to the beta forum. I'm trying to help here, but I'm hoping you have your own real QA people.

So thanks for referring me to the beta forum, but that is unnecessary and quite frankly a waste of a whole post on your part, at best.

Does the manual have instructions about how to generate the LW error log?

Any changes will be made in V14.6, so if it occurs in that version it should be posted there.

Lightworks has its own error log found in Users > public > public documents > Lightworks > logs

Attached a zip file of that would be better than the Windows Application log.

If Lightworks hangs in the background, which can happen, use the task manager to kill the process. That works reliably. It is not necessary to restart the machine.

The process name is "ntcardvt.exe". With Win10 it appears as "Lightworks Editor Application" in the task manager.
It's better to travel well than to arrive...
