Hi there!

Sorry to hear you're running into this issue. I’ve tried to reproduce it on my end but haven’t had any luck so far.

Could you let me know which platform and operating system you’re using with FlutterFlow, as well as the version you’re currently on?

If you’re able to recreate the issue in a new blank project, that would really help speed things up on our side.

Please also send me the bug report code from that new project so I can take a closer look.

Thanks in advance!

As it turns out when i paste it onto a new project from ffdesigner it works , i also deleted all the custom colors that ffdesigner added when i pasted the frames before , but still on my current main project if i try to paste it just crashes and hangs

in a blank new project the ffdesigner to flutterflow copy paste works i dont know why
here is the blank project's bug report code

Hello! Thank you for the additional information. Based on this, we can confirm that the issue is occurring in a specific project and is not a reproducible bug.

In this case, the best next step would be to contact support via the in-app chat, where the team can help you troubleshoot the issue within your project.

As an alternative, you could also try duplicating your project and copying your design into the duplicate. If that works, you may be able to continue working from the new duplicated project.

Best regards
