I've had this problem for a while but haven't had time to investigate.

The latest production build that I can run successfully is 19.5.493. All the ones that I've installed appear to run, the UI appears then they immediately shut again.

Builds I've tried are:
19.5.534
19.5.569
19.5.605

Anyone have any ideas what might be causing that? Windows 10, AMD Ryzen 95950X, RTX 3090.

Thanks for reading

All those builds run fine on the same spec machine here, except RTX A4000.

I would uninstall all hou, delete the preferences folders, make sure you have no external plugins running.
Re install, and in houdini.env set the HOUDINI_DSO_ERROR = 3
This will output pretty verbose level of DSO loading errors, and should help you figure it out.

I was hoping not to have to sift through my preferences and weed out what it was...

I had a suspicion it could be something to do with Redshift so I removed my RS package and all fine now!

Thanks for the input anyway

It's very rare, almost unheard of that houdini won't load.
101 thing to do is to disable all plugins, and go from there.


Glad you're sorted.

thanks for the input Lewis
