Good day.
We confirm the problem with REST API query (hls_store_segment_in_memory does not affect, the problem is reproducing with default settings too). Raised the ticket WCS-3959, will let know about progress here.
The only workaround is temporary downgrade to build 5.2.1776.

The issue is fixed in build 5.2.1789. Please update and check.
