"Platform AndroidPlayer does not support graphics device type OpenGL ES 2” warning is thrown when opening a specific project

Unity: Android

6.0.X

If project has old no longer supported gfx API set in player settings, Unity gives an error when project is upgraded, so you know.

Reproduction steps:
1. Open the “ASDQWE” project
2. Observe the Console Window

Expected result: No warning is visible
Actual result: “Platform AndroidPlayer does not support graphics device type OpenGL ES 2” warning is visible

Reproducible with: 2023.1.0a19, 6000.0.19f1
Not reproducible with: 2021.3.43f1, 2022.3.46f1, 2023.1.0a18

Reproducible on: Windows 11

Notes:

The Android Platform is not selected or installed when the project is opened
Removing the Library folder does not prevent the issue
The warning is only thrown the first time the project is opened and does not occur again
The warning is also thrown when there are compilation errors and the project is opened in Safe Mode
