Bubble is a heavy app on the browser and consumes a lot of RAM. Clear your browser history, close all other apps, use only on editor tab, and … consider using reusables in your app (in case you are not doing so).
As for the pasting problems with flows … I see that you are using the experimental (or … beta) flow editor. Consider reverting back to the good 'ol horizontal one.
My system has 128GB of RAM, with only 20% used, so resources shouldn’t be an issue.
I’ve rebooted my computer, cleared the cache, and even tried different browsers (Chrome, Brave, Arc, Opera).
I also tested on another computer, same error.
Used a VPN, change to 4G/5G and same error.
Tried accessing the editor on an iPad, same error.
Regarding the UI:
The bug first appeared in the horizontal UI, so I switched to the new Workflow UI to see if it would help, but unfortunately, the same error happens in both UIs.
Additionally, the problem isn’t just with workflows—it also happens when I try to copy elements or reusables like groups, text, etc. It’s the same freezing/crashing behavior every time.
If you or anyone else has any other ideas, I’d be super grateful!
