LumenRT Scene-Opening get error at 99%

The LRT 16.16.44.034 was uninstalled and re-install just now, But the Scene-Opening get error at 99% , can not be opened any more .

The latest version(16.16.44.66) gets the same error.

I have sended the report to you at Error Report dialog.

All the feature was installed correctly.
