User receiving "Could not find ancestor view in stack" error message

I have a Desktop app that only a couple of users are active in. This week, the user who is most active, started getting an error message when performing a Save on a certain Form view. There have been no changes whatsoever in this app for over 9 months.

It does appear the activity completes as expected but the user is presented an error message they need to click through.

There is an action on Form Save that adds a set of rows to another table and then navigates the user to a table view of the newly added rows in Edit Mode.

All of this functionality work perfectly for me and another user. For the problem user we have tried Syncs, refreshing the browser page itself, clearing cache, and even restarting the desktop machine. The error persists.

The error message presented looks like this:

The text of the error message behind the button is:

Error id: 466881

Stack: Error: Could not find ancestor view in stack for {“Type”:“Control”,“Name”:“Metric Months_Form”}
