Hi,
You have already reported the same thing here: https://forum.corona-renderer.com/ IR stuck in Parding and Geometry
The known workarounds so far are:
- editing the XPresso setup (not sure what exactly is causing the problem though)
- removing XPresso from the scene (remove/disable the XPresso tag)
- disable expression execution in scene settings: https://forum.corona-renderer.com/ IR and Xpresso issue #msg237151
Hopefully this will be fixed in the upcoming hotfix.
