Unable to load my app, copy or go back to old version

AppSheet AppSheet Q&A

​Hi everyone,

Here is my problem.

A database column deletion followed by a table regeneration caused a fatal schema mismatch. The app definition file crashed mid-generation, and version 1.000144 is now permanently corrupted (“is not runnable”).

​Because the app definition is corrupted, the AppSheet Editor throws a 404 error and an infinite loading loop. I am completely locked out of the UI and cannot access Manage > Version History to perform the rollback myself.

​App Details:

​App ID: b55a8968-0c98-455c-af9e-1bd0c2606a51

​Here is the Audit Log capturing the crash on AppStart:

{

“IfModifiedSinceDate”: “2026-06-30T10:57:51.3317362Z”,

“appStartTime”: “06/30/2026 12:22:21”,

“AppTemplateName”: “b55a8968-0c98-455c-af9e-1bd0c2606a51”,

“Operation”: “App sync”,

“RecordType”: “Stop”,

“Errors”: “App ‘b55a8968-0c98-455c-af9e-1bd0c2606a51’ version 1.000144 is not runnable — please contact the app creator.”,

“AppDefinitionChanged”: true,

“Result”: “Failure”

}

It doesn’t even recognize me anymore… I tried to copy. Copy are stucked, spinning endlessly, and unable to delete them. I don’t know how to get rid of this copies that are not working and can’t be deleted. And I don’t know how to fix my corrupted file now…

Please contact Support for help with this.

I’m sorry for asking that. I feel stupid. But I tried to contact support through help center in appsheet and my related Google workspace but I don’t know how to contact them.

Attn @Jose_Arteaga @Shourya_Tomar

This is a real problem:

Users do not intuitively think Support is to be found by navigating to the Documentation site and looking for a link to Support there.

The notification in Appsheet help center:

Starting June 1, 2026, AppSheet support for Workspace Admin creators will transition to Google Workspace support to provide a more tailored experience.

And the reply of Worspace Support:

I can only provide support for Google Workspace products. Since your question is about AppSheet, which is not a part of Google Workspace, I am unable to assist you with this request.

Ha! Google is incompetent.
