The behavior matches #62547 but it happens only on Android CoreCLR (x64). It's always System.Security.CryptoGraphy.Tests and on that configuration this test has 100% failure rate.

It started on 8/11 but that's when we enabled these tests on that configuration, so it's likely the test has been failing on the configuration "always".

The test should be disabled for CoreCLR Android already, the question is why does it run anyway?

https://github.com/dotnet/runtime/blob/3c6b264bbf078d17db33cb8242cd3de24260af8c/src/libraries/tests.proj#L227-L232

EDIT: They probably need to be removed from the smoke tests as well, I will do it.

Closing, as the 24-hour count is 0 and the failure was resolved in #118733. Furthermore, there's a tracking issue #62547
