I'm also seeing System.Text.Json.Tests.Utf8JsonWriterTests.WriteRawMaxUtf16InputLength fail a couple of times with OOM in the same build. It all impacts Debug builds on Windows.

The test was disabled on Linux for similar reasons. I've posted https://github.com/dotnet/runtime/pull/89442 which disables it altogether.
