Since upgrading from Enterprise 11.1 to 11.5, we've encountered several issues—many of which appear to be related to ChunkLoadError. I've tested across multiple browsers, and behavior varies between them.

In some cases, maps or specific elements fail to load in Dashboards; other times, tables won’t appear in Experience Builder’s table widget. Performing a hard reload and clearing the cache temporarily resolves the issue—missing components will reappear—but the problem tends to resurface later the same day in different dashboards or apps, requiring the same steps again.

The issue appears to be random, with no consistent pattern in terms of when or where it occurs, and it’s not limited to a particular browser.

Possibly.  You can check browser console for the ChunkLoadError messages.

The patch fixed the issue for us.
