Exporting fails/hangs in 10.2.3/El Capitan: Error: This is null

Exporting fails/hangs in 10.2.3/El Capitan: Error: This is null

After recently upgrading to FCPX 10.2.3 and El Capitan I am having inconsistent problems exporting projects. When I go to File>Share… the export just hangs. It stays in the Background Tasks window for about 10-15 minutes, then I eventually get the "Share Failed" notification (error window screenshot attached).

Details:

This happens with any kind of export: Master File, a preset, my own configured setting - happens to them all. Happens with exporting a full project, or just a range selection.
Only happens after FCPX has been running for about 30 mins. When I start, I can export fine, using whatever setting. So whenever it hangs, I restart FCPX and can share the project. I just, obviously, don't want to have to restart the app every time I need to export.
App Nap is off
I've deleted preferences, deleted FCPX and reinstalled from the App store. I've used Digital Rebellions FCS Remover and reinstalled. I've deleted renders. None of this has helped.
This has never happened on any previous version of FCPX or the OS. My FCPX 10.2 on Yosemite worked like a dream. I updated FCPX to 10.2.3 and to El Capitan at the same time and this started happening immediately.

Tech Specs:

Running on a 2013 Retina MacBook Pro, 2.6 GHz, i7
OSX 10.11.3
16GB RAM
NVIDIA GeForce GT 750M 2048 MB
External Apple Thunderbolt Display

Any thoughts or solutions would be greatly appreciated!

Thanks

AAre you using a time code generator effect ?

I am not using a Timecode generator effect in my project.

I am using FXFactory's Timecode plugin - but that's just for a moveable TC display - not a part of any project.

One of the configured presets I use a lot uses the Timecode Generator video effect that is applied on export, but as I say, I'm having the same export-hanging issue no matter what share option/preset/master file I try to export.

Thanks for the info!

Hmm, odd. You mean, specifically, a timecode generator in my storyline or project somewhere? I haven't used any, anywhere in the entire Library. (Also, I'm having this issue in more than one Library.)

I do have the Timecode Generator Video Effect in my custom export preset - but that is not in the timeline anywhere.

Also, after testing some more - I guess exporting the Master File (ProRes in this case, same as the Render format) worked fine. It's the compressing down using the preset where the trouble is.

You mean a Compressor preset that includes the TC effect? Tthe error message indicates a problem with a timecode generator effect during export.

Yes, the TC Effect in Compressor.

There are no generators of any kind in my project (screenshot attached).

Also attaching a screenshot of the Compressor Inspector of the preset. Although this hanging at export is happening with other custom presets as well.

Did you ever manage to solve this?

I have exactly the same issue; it started at a random time (not after any update or anything) and it is killing me.

No TC effect, but all sharing functionality (except Master File) hangs at 0% and then fails with the "this is null!" error.
