What could be the reason for the 'Loading chunk 436 failed' error?

Question

Angular

When loading the admin and dashboard pages, an error pops up in the console: ERROR Error: Uncaught (in promise): ChunkLoadError: Loading chunk 436 failed, but there is no transition. The rest of the pages work great. What could be the problem? I will be grateful for the answer.
