Thanks! Tried those and looked into the thread. For anyone in the future:
- started the project without the plugin
- made a new level and set it to default
- installed the plugin and saw that an object from the initial level was causing the crash
- clicked the link to ‘fix broken objects’ right above the outliner
- restarted the project with Houdini Engine installed. It worked but all the .hdas in the level were gone
Also had to go back and forth a couple of versions because Unreal was failing to create a session. Couldn’t find a way to get the .hdas back though
