My Umbraco site is integrated with Okta for user management. After logging into the site, Umbraco Forms no longer load. Instead the page errors with:

System.InvalidOperationException: Unable to convert user ID (00u2s14m1uDlqcf1Q697)to int using InvariantCulture at Umbraco.Cms.Core.Security.UmbracoUserStore`2.UserIdToInt(String userId)

The call stack is quite long, and mostly Umbraco methods calling each other. This is the first line in the callstack that is actually my code:

@await Component.InvokeAsync("RenderFormScripts", new {formId = form, theme = "Facs"})

If you don't log in, you can access the page just fine.

Sometimes the page loads with a different error message:

I've been digging around that cshmtl file and stepping through my code. I can't find that userId anywhere and I don't recognize format of it all. Any idea whats going on???

Edit: here is the call stack
