Points will not render in Web App Builder if labels are added

Question

In ArcGIS Enterprise I have a web map that is being displayed publicly with web app builder. I've added an address points layer (published to our AGO, and available publicly). The points draw fine until I add simple labels, then they no longer draw at all. They display fine in the webmap, but not at all in Web AppBuilder. This application has been around a long time and this just recently became a problem.

They do show in Map Viewer Classic.

We are on Enterprise 11.2. I have tried it on other browsers and it doesn't work on any of them.

Have you checked whether the labels are showing correctly when opened in Map Viewer Classic? Map Viewer Classic and Web AppBuilder use ArcGIS Maps SDK for JavaScript 3.x while the new Map Viewer uses ArcGIS Maps SDK for JavaScript 4.x. If your labels use something only available in 4.x, Web AppBuilder won't be able to render them.
