UEFN buggy after long period of time session?

I’ve been experiencing this since day 1 of UEFN that has been causing me difficultly to use UEFN after a long period of time. A fellow creator has come forward explain they’re having the same issues as me. Lastly, there is no error codes to these issues. I’ve attached two video proofs of the bug report via google drive. I hope this reaches to the correct team to help understand what preventing from the session to run for a long period of time. Thank you.

@SkylarGemDragon Thank you for your report! We would like to look into this further, would you be able to submit a bug report using the form available here? Fortnite Creative

I’ve already sent a report. Trouble with the new reporting system, it’s difficult to explain about the issue when it’s clear to attach video/image proof. I was hoping the forums would be easier to show the proof of the two issues.
