Build error leg or test failing: R2R linux x64 checked (azurelinux.3.amd64.open.rt) — Interop/TypeMap/TypeMapApp/TypeMapApp.cmd
Pipeline: runtime-coreclr crossgen2 outerloop (definition 134), branch main. The TypeMapApp interop test fails at runtime on the crossgen2 R2R legs: TypeMap.Validate_BlobOnlyAttributeTypeNames throws System.IO.FileNotFoundException from TypeMapLazyDictionary.FindPrecachedExternalTypeMapEntry, so the test returns 101 instead of 100. The failure spans all R2R Interop work items (24 failed work items in source build 1571879) and reproduces in follow-up build 1573564.
This is a runtime execution failure distinct from the earlier crossgen2-compile-time assertion tracked in #126479 (closed; that was an ILC EmbeddedObjectNode assertion during R2R emit, not a runtime FileNotFoundException).

Duplicate search
Searched open/closed issues and PRs for Validate_BlobOnlyAttributeTypeNames, FindPrecachedExternalTypeMapEntry, and TypeMapApp. The closest prior issue, #126479, is closed and covered an ILC compile-time assertion (EmbeddedObjectNode.get_IndexFromBeginningOfArray) rather than this runtime FileNotFoundException, so it is a different failure shape.
