Unhandled exception in Microsoft.Web.WebView2.Wpf.WebView2.Dispose

As this happened once on a client machine, all I can give you is the error as it was logged in the Event Viewer:
Description: The process was terminated due to an unhandled exception.
Exception Info: System.InvalidCastException
at System.StubHelpers.StubHelpers.GetCOMIPFromRCW(System.Object, IntPtr, IntPtr ByRef, Boolean ByRef)
at Microsoft.Web.WebView2.Core.Raw.ICoreWebView2Controller.get_CoreWebView2()
at Microsoft.Web.WebView2.Core.CoreWebView2Controller.get_CoreWebView2()
at Microsoft.Web.WebView2.Wpf.WebView2.Uninitialize(Boolean)
at Microsoft.Web.WebView2.Wpf.WebView2.Dispose(Boolean)
at System.Windows.Interop.HwndHost.Finalize()

The next message in the event viewer then reads:

Please note that I have Runtime 116.0.1938.62 on my own machine and I did notice an occasional error being raised during debugging but it never caused our application to crash so I never paid a lot of attention to it. Sorry. My own machine is Windows 11 22H2

Regression
Was this working before but has regressed? Unsure
If yes, what version did this last work on? Unsure

Repro Steps
Unsure. User stated the application just "crashed"
