Can't create New Cumulative Update

Hi, I think there is an error/bug when creating a new cumulative update. The progress bar disappears at around 60%. There is no error message. The only option is going ‘Back’. I can’t see or submit the new report. Can someone from Quickfile check please? Thank you.

Update: After trying 6 to 8 times it finally worked and I was able to check the report and to submit it to HMRC.
