Level didn't show up in viewer after enabling LPV and cloning the project

Want to test LPV dynamic global illumination so I first edited the ConsoleVariables.ini file, started the Enigne and cloned my project.

In the cloned project I received many notifications some assets was updated, so I reloaded it.

Launched the level it shows up with some missing assets. Deleted the cloned project, deleted the ConsoleVariables.ini new entrey and reopened the original project, now the original project level did not open.

All appear to be fine, the asset can be inspected, size of his elements calculated, etc, just didn’t open op in viewer.

A bit desperate since I worked a lot on that project, my first finished generating a product video.

Just to let know for some reason the editor just hide the viewer, needed to reopen it in View and all is working again.
Silly problem, just was not expecting this.
