Localization Error: "The value of offset is out of range" when switching from sub language to main language in Designer

Hi everyone,

I’m currently working on a multi-language site in Webflow using the built-in Localization feature.

While editing in Designer, I encountered an error when trying to switch the language back from sub to main. The following error appears:

The value of offset is out of range. It must be >= 00 && <= 17825792. Received 17825793

Once this happens, I can’t switch back to main — the Designer interface freezes or displays the error persistently.

Has anyone encountered this error before? Is there a workaround or fix?
Any help would be greatly appreciated.

Thanks in advance!

For future people.
In my case, the error means that the data is corrupted and cannot be restored, apparently.
They say the only way to port it is to restore a backup or start a new project.

I hope you all do not encounter this bug!
