Creating a new UXP plugin via the “Create Plugin” interface and selecting any template plugin will crash inDesign when that plugin’s “Show Alert” command is ran. I have been able to replicate the error on five different Windows 10 systems and one Windows 11 device (with a clean install of Win11, an…

Have you added the enableAlerts feature flag in your manifest? https://developer.adobe.com/photoshop/uxp/2022/uxp-api/reference-js/Global%20Members/HTML%20DOM/alert/

I have not attempted to modify the plugins while working with Adobe support as they are the out of the box starter templates directly from Adobe. If they don’t work out of the box without modification, Adobe must modify their source code directly so that they work without modifications, or resolve …

If it’s non-functional, why is Adobe including it in their template plugins? This seems like a massive oversight on Adobe’s part.

As far I know alert was put behind flag because it caused problems/crashes and it is not recomended to use it. You can make your own dialogs but it will be likely async.

Engineering is looking into this.

An intermittent update: The alert that’s leading to the crash isn’t a UXP alert but rather an Indesign Alert, so the recent changes related to alert deprecation in UXP aren’t applicable here (which as the OP commented, doesn’t alleviate the situation). Also, this is specific to the Windows platform …

Appreciate the update! Would this kind of fix be deployed in a hotfix or would it need to wait until the next major .X version?
