UI Composer/UI Builder does not open correctly in AppGyver

[kevin-wu]

After trying to add a repeated item to a customized List Component, I got an error below and the UI builder never shown correctly. There's always a popup asks me if I would like to revert or save the unsaved work.

How can I solve this issue?

Note: I already tried to clear the cache and re-login from a clean browser. Still not working

Which edition of Appgyver are you using?

Can you revert and then things go back to normal? If so, can you show more of the component you are building.

Where is the error message displayed?

[kevin-wu]

I use the new and latest community version.

No I can jot roll back to because the UI is not loaded correctly and the Revert button is not working.
