Reproducible with: 2022.3.17f1, 2023.2.4f1, 2023.3.0b1
Couldn’t test with: 2021.3.34f1 (due to the warning confirmation not existing)
Reproducible on: Windows 11 Pro (22H2)
Not reproducible on: No other environment tested
Notes:
1. Maximizing and unmaximizing other windows (Hierarchy window, Inspector window, Scene View, Game View) instead of the Project Settings window in step 5 does not reproduce the issue
2. Maximizing and unmaximizing other windows instead of the Project Settings window after step 8 fixes the issue and the Diagnostics tab is accessible again
