Are VST3s working? Exponential Stratus 3D VST3 crashes DP

[dix]

Anyone using iZotope (fka Exponential) surround plugins with DP? I recently bought Stratus 3D, and can not get it to play well with DP.

Reopening any project with Stratus VST or AU crashes on Open. Instances on Auxs don't crash DP, but any project that has an instance of Stratus on an Instrument track or an Audio track will crash on Open.

This points to a possible Pre-render issue, but projects with an instrument that have outputs (with Stratus inserted) that are bussed to an Aux also crash on Open. Also, toggling Enable/Disable on an Aux Return with Stratus inserted causes an immediate crash....which essentially makes Stratus a non-starter.

I'll start a MOTU TechLink and contact iZotope. Please let me know if anyone has any suggestions or experiences that might help. Thx.

Upon further troubleshooting it looks like only Stratus 3D consistently crashes DP as described above. For whatever reason the "3D" plugin only comes in VST3 format. Are VST3s generally working and stable with DP? I know they're newly implemented for DP. This is the first VST3 plugin I've tried....and failed, to be able to make work.
