@lewing looks like Android specific, can you please help route it?

The Expected: NaN is extremely suspicious here since that is the expected value in this assert which should be 2.3:

runtime/src/libraries/System.Text.Json/tests/System.Text.Json.Tests/JsonNode/JsonArrayTests.cs

Line 435 in c302b7b

Assert.Equal(2.3, mixedTypesArray[4].GetValue<double>());

We recently did a major change to the x86 floating point handling in #65723, there's a good chance this is fixed by that.

Let's keep an eye on it and see if it happens again.

I don't see recent failures for this one so it is presumably fixed by #65723.

Closing.
