Hey Mamouf,
Sorry for the delay on this one.
I’m unable to open the project due to the dependency on Advanced Sessions, and oddly enough I’m unable to disable the plugin either in the normal fashion.
However, what I’d recommend, since I’ve been able to reproduce the issue in vanilla Unreal, is to remove the plugin completely and test it to see if the same issue occurs. If it is determined that the plugin is the cause of the issue, you’ll need to get in touch with the plugin’s creator in order to get support.
Let me know if you have further questions.
Have a great day
