Build FAILED.
This was first seen in the CI for the PR to update us to using net11 TFM #5064, which was merged as all runs were broken before. The cause of this error is unclear as the GetCurrentHashAsUInt64 still seems to exist in dotnet/runtime main branch. The SDK version that this is happening on is: 11.0.100-alpha.1.25608.101 which was setup using dotnet-install -Channel 11 -Quality daily.
