The closed https://github.com/dotnet/runtime/issues/105177 looks somewhat similar, but I have no idea if it's actually related.

Start with WaitForReadsClosedAsync_ServerReadAborted_Throws in src/libraries/System.Net.Quic/tests/FunctionalTests/QuicStreamTests.cs around line 874, then read QuicTestBase.cs around lines 222-342 and the QuicConnection shutdown handling around lines 654-803. Re-run the named functional test and inspect the timeout and unobserved QuicListener disposal exception. Done means the test completes without the inactivity timeout or related cleanup failure.
