STATUS_APP_DATA_CORRUPT
Fast Cache metadata failed validation
STATUS_APP_DATA_CORRUPT identifies a specific Windows status in the application packaging and activation path. The cache entry was found but could not be trusted structurally or semantically. This is different from a simple cache miss and warrants preserving the failing record for diagnosis.
Correlate the failure with disk, profile, update and package events; let the owning Windows component rebuild the cache instead of editing opaque cache files.
What to preserve before changing the system
- The exact API, caller, target object, original NTSTATUS value, and any nested error or activity ID.
- the relevant process token, package/job/enclave identity, lifecycle state, and policy or mitigation settings.
- operational event logs and a timeline showing the first transition into the failing state.
