Reproduction steps:
1. Create a new project
2. Go to Project Settings
3. In the Player settings, find and change the HDR Cubemap Encoding (example: from “High” to “Low” on a desktop platform, or from “Low” to “High” on the Android platform)
4. Close and reopen the Editor
5. Observe the HDR Cubemap Encoding setting

Expected result: The setting stays as it was set
Actual result: The setting is reverted to the default one (“High” for Desktop platforms and “Low” for Android platform)
