Map Feature layer data failing to Load

This is regarding an issue with the visibility of map data points in our report, where the points suddenly stopped displaying on the map. Previously, the feature map point layer was loading and rendering the data points correctly. However, the issue is now occurring with any newly created feature point layer, regardless of the size or volume of the layer.

The data retrieval process from ArcGis is functioning correctly, and we are successfully fetching the data. However, the retrieved data points are not being plotted on the map as expected. The data remains visible in the grid/table view within our report, which confirms that the data is available but not rendering on the map layer.

Additionally, when we attempt to open the feature layer in the ArcGis Map Viewer, the point features are not rendered on the map. Even after applying filters within the Map Viewer, the data is visible in the table view, but the corresponding points are still not displayed on the map.

Currently, we are using two separate map feature layers with approximately 7,853,238 data points (CSV size: 819 MB) and 17,630,430 data points (CSV size: 1.7 GB) respectively.

We're using : "@arcgis/core": "^4.21.2",

Number of points and size of the dataset aside, have you tried to condense things into a testable layer and have you delved into your browser too, just to make sure you're not hitting any issues with caching. I'll be honest, I'd never attempt to render that number of points without a suitable cluster on first.
