White page in the editor and global error starting preview

Not sure if this is related to an update of Vuforia Studio Editor:
When opening some projects during the loading process, something goes wrong and while the 3D viewport in the editor is loading, suddenly it becomes completely white. Also, the hierarchy results as empty.

When this happens, I don't see any error in the log, but if I try to launch the preview I receive a Global error and in the log, I read:

Error: Invalid glob argument:

I've already tried to re-install Studio and removing some projects that I thought were causing the issue. But didn't solve completely.

Thanks for your help!
