Resolution Note:
This has been fixed by an unknown PR.
Confirmed that 2023.1.0b9 has the issue however later versions do not.
Tested 2023.1.5f1, 2023.2.0b9 and 2023.3.0a1.
Note: This bug is only looking into the error with regards to the preset window, not the error message in general which can occur under many different circumstances.
